Unfortunately, my cat chewed off my 40-pin usb charging cable and I'm going nuts atm... so has anyone found anywhere that might sell a cable like this? I looked pretty much all the online places and they're none existence, perhaps if i take it to local phone shops, will they be able to solder it up?

To be honest i do not think they sell those separately yet
My first guess is to call Asus directly, and tell them what happened and they might send you a new one or let you buy one over the phone if you feel comfortable doing that
Or even contact them on Facebook they actually monitor that very well
As for the cable splice, i am not sure of any phone shops that would do that, at least in my area, maybe a electronics repair shop would be better, probably charge you an arm and a leg though
If i had bought a dock with my transformer, i would send you my extra cable

No extra cable with the dock...unless I got shorted one.
So I spent over an hour talking on the phone with them this morning, apparently, they don't even have a part number for the cable, I even had to convince them that this doesn't sell in the local shops first. Now they're saying there'll be a "special" team which will contact me within 24 hours to solve the problem.

Asus were brilliant for us when my Mum had a problem with her Eee PC a couple of years back - screen failed, got a brand new one within a week. Couldn't argue at all!
It does seem vary by product, hopefully they'll contact me soon.

Don't tell them your cat chewed it. You're better off saying it's defective and the store won't take it back and demand a replacement. When they get yours back they'll charge you for the cat-chewed cable and everyones happy.
Telling them it was your fault will not get anything done quickly, because they don't have to give you a new one. Try it the other way around and at least you can get a working cable and they'll charge the money it would have cost to sell it to you.
Hope it all works out.

My bad, i thought the dock came with a cable because that would be the most obvious thing to include , guess i was wrong lol
I called again later and on the third time was able to get a RMA for it, sent it to the service center right afterwards so hopefully I can get a phone call sometimes next week about the payment. But from what they said, it seems like they don't have these things on stock for replacement, kinda sucks since I'll be out of country in a week and half.
I've never repaired a cable before, so I haven't a clue what I'm talking about, but if the wires inside of the cable are color coded, I bet with a pair of wire strippers and a little solder and electrical tape, you might be able to do the job yourself.

I peaked through the opening of the cable, the wires were extremely small where I could not see the inner metal wires within the cables and they seem like un-strippable (so thin that I'm afraid to break it with typical wire stripper), also there're metal wires on the outside wrapping the inner cables which are also damaged. Just gonna give up and let them send me a new one.
ASUS suggested website
BTW, one of the reps were telling me to go to this website and check if they have the cables in stock http://www.asusparts.eu/index.php
I think this will be the first place to have them if any charging/replacement kits would be available. However, currently there're nothing related to the TF.

I found out that they listed them over last weekend, also sent them an email asking when the cables will be available.
They replied:
transformer is now delayed to mid-June.
Sorry to have to give you the bad news...
But im not sure if they're talking about the tablet or cables, gonna ask them again and see what they reply.
Sorry you are having to cope with the problem. It's got to be very frustrating. I'm waiting for my TF to arrive from Amazon. It will be at least a month from order to delivery, but that's got to be less frustrating than having it in your hands, and not being able to use it.
I'm sure the USB connection for charging uses only 3 or 4 wires, so it might be relatively easy to temporarily wire it, but at best, it would be highly vulnerable to breakage. I think you made the right choice to RMA it back and get a new one.
I have a quick question for anyone that already has a charging cable. Approximately how long is it? I looked at the picture in the link, with it wrapped up, but it doesn't look very long. Anything less than 6' will be less than perfect for me, although I could use a USB extension cable if necessary.
My power adapter died on me today!! I can charge with usb from my PC and now im using an old iphoneac adapter to charge with. It is really slow though, gained 1% in about 10 minutes....

Find a universal USB charger for an iPad. It should charge the TF while powered off, or at least with the screen off. It will take longer to charge, of course, but it should do the job.
Thread for hardware mods
POSTING INTERNAL tf101 pictures
like 3g dongle ? internal sd cards? ssd?
removing the battery for 2 HDD 500go?
finding sd cards hubs? usb to sata cables?
? there is a place in the tablet for a 3g dongle?
there are 2 screws under the upper rubbers and the dock open easy
there is a lot of spaces avaible
My MIFI might actually fit in there, all I would need to do is supply it power somehow.
I'm no hardware engineer though, but if thats possible it would save you from the driver issues with a 3g dongle.
I wonder if it would be possible to check which pins from the adapter connect to USB - so we can make DIY USB adapter for those without a dock.
hmm adding an hdd would be very interesting, sata won't be very hard, powersupply will be.
Sent from my O2x with CM7
This is what I was looking for, looking to do some mods to the dock.
Thanks Markolino72.
Internally mount and wire a 32gb memory stick to the USB port so you get a 32gb hard drive added whenever you dock It might even have enough room for a portable USB hub so you don't lose use of the external usb port?
does anybody think it will be easy to make a DIY dock fix for those with battery draining issues like me?
It seems like it would be relatively easy - just make a switch to either connect or disconnect the cords coming from the docking point.
Or even better, maybe if you put the correct microcontroller in there you can have it switch the pins to floating, if it senses that there is no tablet connected (not sure about the details though)...

Have you seen the post in the General forum (2nd page now I think)? Posted by Asus_USA themselves, if you prove the 6 steps that your dock has the issue you can get a new one! I really do hope that I can get mine exchanged, waiting on a reply from my local service center..
Regards.
In regards to the hardware mods, that really looks amazing. Would love to put in my mifi there as well, attach it via USB to charge = your own 3g model Maybe a little modding you could get the mifi to power on only when the dock is connected (remove the battery of the mifi?) so that when it powers on it'll power on the mifi as well. Only a few thoughts.

it's a good thought but the mifi I have (novatel 2200) wont work without the battery, for some reason if the battery is bad or removed you cannot run usb, it must be the way they have the power run through the battery or charging. Not sure if all are like this or not.

I talked to the Asus service rep about it. They currently won't give you a new one since they have a hardware upgrade to fix it. If you wanted a new one you needed to do before they solved the problem. I'm waiting on the upgrade part to be delivered for for mine. Should in a few days.
A switch should theoretically work. The guy at the service center said the replace something that goes into the hinge of the dock. Looking at the teardown pics, you can see a wire goes into each side of the hinge, so I think they replace the wires and maybe make a new connection somewhere on the dock.
Surprising how much wasted space there seems to be in the dock -- it's nowhere near as tightly packaged as the tablet itself. Looks like Asus can optimize the size or fit some more features in future versions, if they want...
Let me see if I am thinking correctly...Your saying using something like mifi installed via USB wires (will it be always on?) then connect via WiFi on your transformer? So basically your putting the mifi in a case that can never be opened without a screwdriver? I guess one would always have access for your other devices as well as long as the TF is in the vicinity.
P.S. I think I think this is a good idea, not decided though. I like to think of it in a real world application.
there is another post with a guy putting in an SSD, but it bulges at the keyboard. A 32g SD card would be nice.

Well I ended up calling them. I would have to ship the dock to "someone" in the US, have them ship it to the repair center, fix it, ship it back and then ask that "someone" to ship it back to me... sooo, I'm basically screwed... I ended up with a nice 150US paperweight (not even considering the horrible light bleed on the transformer).

Yeah, actually, I hadn't realized that but it does say it clearly on the product warranty page:
"Brazil and South American countries don’t support global service"
http://support.asus.com/warranty.aspx?SLanguage=en&p=20&s=16&m=Eee Pad Transformer TF101
took mine apart also and there is quite a bit of room.
i plan on putting a 128gb usb flash drive inside the dock and soldering onto the usb connections once i get all the bits in.
Any bigger pictures? Are the screws under the rubber feet?
just two screws under the rubber feet near the hinge then it just pulls apart from the top
had to take mine apart as the spring/clip mechanism for the sd card wouldnt lock the card in.
now the card is stuck in with no nails haha a simple fix.
This is good news. I hacked a Crystal HD decoder card (pcie), USB wifi dongle, a logitech nano receiver, and a 4 port micro usb hub (from a touch screen setup) into a Dell mini 9 and there was absolutely no room compared to this.
They even have covers for the USB ports, so if you remove a header and solder wires up you just have to hot glue / epoxy that cover from the back and you are money. Looks clean and stock.
I have an old 64 GB thumbdrive that might find a new home. Maybe a 1.8" usb HDD would fit in there with the battery, without the battery who knows.
I have the official samsung dock and it only charges the phone. If i pull the usb cable out of the dock and connect to the phone it will allow mount of SD and copy / sync of files.
I'm sure a small wiring / circuit change inside the dock is all I need, and I'm pretty sure someone has blazed this trail before. I just can't find their notes on the forums or web.
Any assistance appreciated.

Which dock? If it's the one that has audio output - no you can't use it to sync because it uses D+ and D- for audio L/R.
If you wanted to use it to sync you'd have to remove the ID resistor and reroute D+ and D- back to the USB cable.
Thats what I'm talking about. Are those changes documented somewhere? I don't care about audio out (the dock does have that output jack).

Easiest way to do it is to break off the bottom part and just use the standard cable directly to the phone.
If you were interested you could always try this:

I saw many of those docks for the 9100 also. When I pressed the vendors for 777 compatibility the answer was always "NO". Probably because they just don't know enough for a definitive "YES". Let us know how it goes.
I may just have to break out my kids legos and build something around the plain cable
(that way it can accomodate a case)
The description says it can be used to charge/sync. For $10, I'm willing to take that bet.
It'll be nice to actually have my phone sitting in something while charging over night instead of just laying on my desk.
Our phones are pretty much the same as the international version (with slightly rounded corners and 2nd mic placement) but theoretically the bottom should be exactly the same, so I don't see why that wouldn't work.
Hello everyone,
I understand that the GPS Dongle for the Prime occupies the ASUS 40-pin, which means it won't allow the dock to be used. I'm just wondering whether it is possible in the future to have a cable with compatible ends at both side? Of course it should be male/female to be used with the dock's left hand side female.
This way, theoretically, I would be a able to use my Prime, dock and the GPS Dongle all together while travelling. But I'm not sure that it's possible, even if such cable exists... sometime in the future.
Probably some of you out there have any opinions regarding this matter.
No cable for this currently exists.
However one could be made, if the connector is a straight pass through then it would work. If the connector however only utilizes certain pins then it would either need to be modified or replaced.
Either way it will take some experimentation.
The easy way for now is to remove the device form the plastic housing and plug it into the dock to see if it works.

Yes, I understand that it cannot be done at this moment. But theoretically it might work, right? Or is there something in the dock prevents the GPS to get connected to the Prime? Such thing like, power line (charging) is more priority and is using the same pins?

Theoretically time travel is possible, anyhing is possible theoretically,
But to answer your question, no there are no pins which share data/power.
The only worry is that the dock female connector may only be power and ground, no data, I know this to not be true as I rooted while in the dock, so all pins pass through from what I can tell.
It looks like for ease of manufacture all o the connectors are the same on the tablet, the dock and the dock plug.
A wire or new housing should be easy enough to fab up.
I will test this tonight.

This means we will need to open the dock and connect the lines that are not connected if we wish for this to work.

a little bit pity 'though, since I have a plan to use them all together on the road.
im currently in the process of tracking down which pins are used in the dongle, unfortunately i only have one dock and its too expensive for me to start ripping it apart however hopefully with the information im gathering and information others are gathering we can get a pinout for the dongle as well as the prime and dock to better understand how everything works

I have one of the SD CARD adapters for the prime (I purchased while waiting for the keyboard). I plugged it into the keyboard power port with an SD CARD inserted and the prime did NOT see it.
I think the port on the keyboard is power only
Ok, i know theres a sticky for the GPS dongle but this isnt one of those "Wheres my dongle" or how to sign up threads so i thought it diserved its own thread. If you have questions about how to acquire a GPS dongle or want to say you got yours or whatever this is NOT the place to do it. See the sticky. kthxbie.
Still with me? Awesome! In having multiple primes i have recieved multiple GPS dongles. Since i rarely use one as it is, let alone them all at once i was wondering what sort of tweaks / hacks / mods have people tried (or wanted to try but were too afraid of screwing up their only dongle) that i might do on my extra one?
I already plan on doing a full teardown, taking highres macro pictures of the connector as well as unsoldering the shielding on the PCB and seeing whats underneath. Anything else you guys can think of?
Im not too worried about ruining the device if it means i can try something cool! Lets hear those ideas!
UPDATE: isolated the dock connector. Thus far with my tester these pins are grounded: (back view)
_ _ _ _ _ _ _ G _ G
G _ _ _ _ _ _ _ _ _ G
I know theres an official dock connector thread here: http://forum.xda-developers.com/showthread.php?t=1630300 but im not sure which pins according to that thread match what i have here.
UPDATE 2: removed dock connector, looks like only the bottom row goes to the dongle, not sure yet if any of the top row go anywhere inside the dongle or if it terminates at the connector. Will continue to test.
UPDATE 3: Ok, uploaded my work for tonight, traced a few of the connections just to see where everything is going. There WERE a couple that were coming out the top row, the two resisters on top, that MIGHT be the trigger to tell the prime its connected to an external device? who knows. anyways, its very late here, i will continue to test as i have time and as people show interest.
UDATE 5/5/2012
Ok, been doing some research and testing and whatnot, i have some very bad news. In order to attach any kind of connector to charge the tablet with the dongle attached it would mean soldering a wire to four of the pins on the connector on the TABLET SIDE of the pcb, UNDERNEATH the connector (the really fine pitch pins). Maybe i will have to take a picture to show what is needed.
Suffice to say chances of a mod that can be completed by most people out there is very low. I will continue to try to find a solution.
The red square shows which pins would need to solder the 15v+, the ground could be soldered to any of the grount points. (+5v to each of the three pins or +15v to all three)
Additionally, i have been doing some work on the pinout, trying to clean up the information we currently have. No offence to bjonston115 but his thread is confusing since every source has pins labled differently and there is info scattered everywhere. Bear with me as i try to sort the mess out and make something we can all use
You are so lucky. Wish I had a spare. My main hope is to determine who makes the connectors (if possible), and what pins are used inside that connector, along with how it's mounted.
My desire, is to procure a connector, to add to the dongle shell, and the wiring, so I can permit the tablet to be charged while the dongle is in use.
When I drive 14 hrs to FL, my battery will run out, mid trip. So far, my only solution is to carry an external GPS to use while the TP charges.
Looking forward to your teardown.
Bob
Images. Took as many pics as i could as i was removing bits n pieces. If you want a picture of a specific part let me know. Pictures uploading, give me a minute or two...
I think a power mod should be straightforward. The dongle shell looks "thick" enough to accomodate a USB female Type A connector, mounted orthogonally. You'd want one with right-angle contacts similar to the one below, so you can let it "bottom out" against far side of the dongle shell. For aesthetics, I'd dremel the opening at the back side of the dongle rather than front, but this depends on your car mount.
The next step is to solder jumper wires from USB's power and ground pins to appropriate pins on 40-pin connector. Since USB adapter for TF101 is same for Prime/300, we can assume pin-out for USB functions is still same. Somebody already posted partial pin-out in another thread.
Soldering to the USB contact isn't a big deal, but to the finer-pitch 40-pin connector would take a bit of finesse.
Note: TF101/201/300 can charge with [email protected]
@pileot: Suggest taking a caliper and measure inner and outer thickness of dongle (ie w/ and w/o the shell thickness).
http://www.ebay.com/itm/1PCS-USB-sh...ale-socket-Connector-PCB-Socket-/260991770971
unfortunately i dont have access to calipers, far as i can measure outside thickness is about 3/4 maybe slightly less, inside thickness is about 1/8 inches. sorry i cant be more accurate.
im assuming you want to throw a USB on the PCB? im not exactly sure how you want to connect that usb female connector, or what the purpose would be to do so.... Mind explaining just a little more?
Mount: Use dremel to create a rectangular hole (12.5mm x 5.2mm) at the back (or front) of the dongle. Use a short-body USB connector w/ right-angle contact like the previous, and mount it orthogonally, eg perpendicular to dongle facing. I think the short-body one has a length of about 0.5" so it should flush-mount. But if not, having it sticking out a bit isn't a big deal.
Purpose: To charge tablet w/ either [email protected] or [email protected] I would go with the second, since USB car chargers for it are widely available (that's what the iPad uses).

I know that the PC USB charge @~500ma takes forever and the TP has to be shut off, but what would the deal be with [email protected]
Would I be able to continue to use it as it charged, or would it need to be shut down too.
I'd probably use a USB 3 connector in place of the pictured USB 2
Thanks for the idea...I never thought of that....now all I got to do is to wait till I get my dongle.
Bob
ahh! makes sense.... sure would be nice if we had a full connector port. Maybe i could make a trip to an electronic component store and pick up some USB connectors.
If you just want to use it for power then dont we just need any sort of connection to the charging ports and the outside of the dongle? It doesnt have to be USB it could be anything as long as you have a male and female connection

unfortunately i dont have access to calipers, far as i can measure outside thickness is about 3/4 maybe slightly less, inside thickness is about 1/8 inches. sorry i cant be more accurate.
im assuming you want to throw a USB on the PCB? im not exactly sure how you want to connect that usb female connector, or what the purpose would be to do so.... Mind explaining just a little more?

There is a neat tool in Google Play called Smart Tools. Possibly you could get better measurements of the items you want to measure by using the tool, and laying the item right on the screen. I have it installed, and think it was a well done app.

No idea. That's something you can find out afterward. Having the mod in place won't hurt anything.
My guess is that it should be good enough to at least maintain battery level while on, which would be all that's needed in a car.

You can use barrel power connector. But you'd have to make your own power cable, as opposed to using a standard USB cable to connect to the charger. Edit: On second thought, you can use a [email protected] car charger, then get a mating barrel connector.

from what i understand if you have the tablet on and try to charge with 5v it wont even maintain the current battery level. The tablet charges with 15v or something... having a barrel connector would ensure you dont accidentally plug a prime charger into another USB device frying it.
At that point if we could just get the barrel plug right to the power pins, fitting it in should be too hard....I am really interested iin this because I have 2 dongles coming tomorrow annd planned on hacking one....(I got two because one was RMA and they sent me a new one back 2 serials=2 Dongles)

See edited first post. Because the top row does not go to the back of the PCB and i believe thats where the power is, it would be hard to throw a charging circut in there. I am still working on locating where all the pins in this thing go but it is very tiny, even with my finest nodes to test these circuts its very delicate work.
In the mean time, i will upload what i do have before i go to sleep tonight (maybe in another hour or so) so stay tuned!
Okay I will try and keep updated... if we could get a charging circiut in maybe a true car mount might be a project... at least for me, I already have a tablet window mount and with some changes I could affix a modified dongle at the bottom and just slide prime in for GPS + charging (again if we can get it to work)... I get mine today and disassembly will soon follow so I will post anything else I can to help progress

Ok, been doing some research and testing and whatnot, i have some very bad news. In order to attach any kind of connector to charge the tablet with the dongle attached it would mean soldering a wire to four of the pins on the connector on the TABLET SIDE of the pcb, UNDERNEATH the connector (the really fine pitch pins). Maybe i will have to take a picture to show what is needed.
Suffice to say chances of a mod that can be completed by most people out there is very low. I will continue to try to find a solution.
The red square shows which pins would need to solder the 15v+, the ground could be soldered to any of the grount points. (+5v to each of the three pins or +15v to all three)

Okay first off...have we all decided to stay low until we progress, i don't want this thread to die so soon...secondly...though I am sure you have done you research I still must ask, Are you sure? if we can provide any charge to the prime it will at least help a bit...also does anyone one else have other ideas other than charging?...
one idea I literally just thought of so it is not very thought out is, what if we remove the dongle case( as we have done) and integrate it into case.... we will need one of the 40-pin cables to wire onto it but maybe it could fit into some cases.
I will continue to try to think of more uses and mods and will update, meanwhile I hope that we can get some more input
Hmm, you've made quite a bit of progress there. I really wish I wasn't lazy haha, I need to learn to really work with electrical stuff.
So, then the dongle uses some of the pins that would be used for power from the dock? If the dock can pass power without changing the Prime, I should think the dongle could somehow. I mean, only certain pins are used for data right, so the dock and dongle should use the same ones?
Ok, firstly. Yes, im sure. Im sure of the pin placement and based on the best available information scattered around the internet, i know which pins the charger uses and i know where they are located on the dongle. I also know there is very little access to them (as seen in the pictures in OP)
as to integrating the dongle INSIDE the prime casing you would, essentially, be succoming to the same problem the internal antennas have: Metal blocking the signal. Sure its a more powerfull antenna however its encased in PLASTIC not metal, the signal it recieves is a lot stronger and there is less EMI caused by the metalic back plate. Short: Yes you can, no you dont want to.
Finally, the pins the prime uses to draw power are different than the pins the charger uses to supply power. Think one lane dirt road vs a 6 lane highway. On the highway you have dedicated lanes for traffic going in different directions. this is similar to how the prime dock connector works, the prime can turn off power to different connections depending if there is something plugged in reducing the chance of a short, spark, or power drain.
Hopefully this addressed your concerns, maybe when i have apropriate tools handy and a bit of time i may try soldering a connection to the dock connector and see how it functions but as you can see its REALLY tight. I will do my best, no promises.
I also plan, in the near future, to locate more of the data pins, see whats going on, maybe we can make a USB adapter for the dongle and use it in other devices as well! who knows, im thinking it just uses a standard USB interface but it will take more digging.
Subscribed as I see no need for the dongle unless you have enough power.
Though I was pretty sure you were sure I just wanted to ask.... but you did misinterpret my idea, I do not mean the Prime's casing but rather integrating the gps into a case which holds the prime...This is not to say that the gps is big or in the way but just an idea i had to help people with cases and a use for the gps, but since the usb uses different pins that looks unlikely as well i guess...well I will stay updated and if I learn anything I will post.
I would be more interested in adding a power jack of some sort to the dongle. So you can charge while using navigation. I already can not use my dock while plugged into the dongle. We need power!
