Hi All,
So I've spend the best part of the weekend trying to find a wiring diagram for the cable for the TF101.. one of my delightful kids pulled on the wire to disconnect it from the adapter, and left the actual usb plug behind - so I now have a cable with 6 wires exposed, and a seperate (and mangled) usb plug.
I've ordered a new cable - but urgently need to charge my TF101 today... does anyone know where I can find a wiring diagram so I can connect the wires direct to a 12v adapter - or know which of the wires in the cable are + and - ?
many thanks in advance
Nick

Can EEE PAD Transformer support Full USB HOST functionality using stock connector provided by ASUS using something like below FEMALE TO FEMALE USB Adaptor ?
http://www.hkcolordigital.com/usb-2.0-a-female-to-usb-2.0-a-female-adapter.html
I know ASUS dock keyboard do have USB port and also, ASUS is selling USB adaptor for around $45, but I do not want to spend that much.
Since ASUS stock connector which is used for charging as well as data transfer from PC support USB functionality, I believe it should be easy to implement.
Any suggestion/solution ?
Thanks
No, it wouldn't work.

I can't find pinout for ASUS charging connector, but i think it has USB-host pins in it - so you should just solder an USB-female to them in right order.

this might work. USB OTG is what we looking for
USB Adapter Coupler Type A Female to Female
I have ordered "USB Adapter Coupler Type A Female to Female" from ebay ($3 including shipping):
http://www.ebay.in/itm/120868617077?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649#ht_932wt_1143
Once it reaches to me, I'll try what is possible with it.
I received the "USB Adapter Coupler Type A Female to Female" today and tried to connect USB pen drive and as it was expected, NOTHING HAPPENED.
But, I still think it is possible. I have seen Nexus and Galaxy phones with USB host online.
I think, to be precise, it is not only Female to Female adaptor to be connected to stock connector, but it needs some power (+5v) as well. For this, I think it need USB Y Connector, as in attachment. Below is the link for reference:
http://htc-linux.org/wiki/index.php?title=Msm_Usb_Host
Now, I am thinking to open Female to Female USB connector and solder 2-wire with USB Male connector to it (I have extra USB mouse) for power (+5V & Ground) and try again.
look at last link in my previous reply. There are photos of disassembled host adapter and some schematics-pinouts. TF has USBhost, but it on different pins than usb-slave cable.
I have a MHL Adapter and I get video just fine. Now I want to be able to sit on my couch while i use the adapter. Seems to me the simplest way would be to use a 15-20 foot Micro USB Male - Micro USB Female extension cable.
Does anyone have any experience with such a setup? Do you have a recommendation for such a cable?
TIA!!
Why micro USB? You can get a HDMI cable as long as you might want (Monoprice is particularly good). If it's not enough you can carry a HDMI signal over a single or (simpler to find) two CAT5 cables w/ RJ45 jacks for hundreds of feet.
I guess the thought was that if I have the Micro USB Extension, then it's one thin lightweight wire that has to travel across the floor.
If I did HDMI, I'd still have to be near power whereas with Micro USB, I could set the power adapter, and HDMI, and MHL Adapter all together and then have a thin and lightweight wire traveling across the floor.
But if it's not possible, (micro USB limitiation??) then HDMI it would have to be.

If the micro USB works it would be much cheaper than a comparable length hdmi cord.

I would test http://www.amazon.com/Extender-over-CAT5E-CAT6-connection/dp/B003L14ZTC this. It's hard to get cheaper than cat5e.
Just bought 10 feet on amazon! Lovely!

I wanted to do exactly this - extend the cable but at the micro-USB end to avoid having the Micro-usb power supply line and the bulky MHL adaptor all where the phone is - much cleaner to just have a thin cable coming out of the phone and headed towards the TV.
I did get hold of a micro-USB extension cable (2m/6ft) but unfortunately it does not work. Directly plugging the phone into the MHL adaptor works perfectly, as soon as I insert the micro-USB extension it doesn't work. I need to have a closer look to check the pins are populated etc, but not sure why this would be an issue - don't think it can be signal strength and if all the pins are populated I don't see why the adaptor would care.????
Any thoughts?
Micro B USB extension not working
I, too have been trying to figure out why an extension cable doesn't work the way you think it might. Today, I tried cutting my 6 foot cable, first making sure I had the right power leads working. Then I went through all the possible combinations of connections to see if one would work. None do. I'm at a complete loss on this wondering what I should try next.
Thanks for info....similarly baffled but at least you have ruled out something!
Like the other guy said, get your x for of hdmi cable, then just plug your AC charger in where you are. Mhl might use additional connectors/pins/whatever vs micro USB. Or you can go totally wireless and use a Bluetooth mouse and keyboard.
Also I remember I had a charging issue with an extension. Sometimes one product works better than others. I can't charge my phone with my 20 dollar AC charger from best buy since the ICS leak. It's weird. Hdmi cables are pretty uniform, I would just extend that.

Yes, that works, always has, but that's not the point. Would rather have just one long cable connected to the phone in front of the TV rather than three cables, the device and the phone in a kludge setup.
A partial answer
This allows connecting 6 feet away with a thin, flexible single cable..Also cheap, but shipping takes 15 days.

I took apart the two cables and the USB has four wires while the MHL cable has ten.
are the mhl wires easily extendable themselves by splicing? I'm thinking strip out a few usb cables and use the wires? Or just go purchase some extremely thin gauge wire (22 gauge) and make it yourself?
Micro B USB extension not working
The Micro B USB connector only has 5 connections, so there is no way you can connect 10 from the MHL cable to it, so something else is going on.

I bought splices and thought about extending the cable. It's possible.

I did wanted to do the same but the extension cable didn't work. I looked at the connecting points and felt that the micro usb from Mel adaptor is to bit longer than usual so I thought that may be the reason and I shorten it resulting damaging my Mel adaptor itself. Now I am going for allshare cast wireless hub. So everyone please don't try to cut the micro usb pin from your adaptor or u will better decide to for my option to for complete flexibility.
I want to do this EXACT same thing but slightly more extreme:
I want an MHL adapter with 10-25 feet of micro USB cable on the end so I can use it from anywhere in my living room.
Is there any such cable/adapter?
Why do all MHL adapters come with only a 5 inch cable??? It is maddening!
*bump* I am looking for this too.. but I have a reason slightly different.. I have an AppRadio in my car that I connect my phone to. The MHL cable end is rather bulky and does not fit into the opening of my otterbox that is on my phone... most microUSB wires fit into the opening just fine.. Taking my phone out of the case every time I am in the car is rather ridiculous so I bought the micro USB extension (bought a 6" one).. didn;t even register except to charge... So, and ideas would be greatly appreciated..

Get a different MHL adapter. I use an adapter close to the one 7 posts up by hedaleth with my kenwood system in my truck.
First off I'd to say hello from Alaska,
Ok this may sound strange but does anybody out there know where i might find or have one made, I'm looking for a cable with 2 40 pin connectors on both ends, 1 male and the other female. This is for my TF201 and dock, I would use it so I don't have to take off the case to the Prime just plug in to the prime and to the dock..
Thank you all Stan
Cables to Go should be able to do this for you. I've had them make custom cables for me before. It likely won't be cheap, but they should be able to do it.
www.cablestogo.com
Just in case anyone was curious, I thought I would try to get lucky and see if a female-female USB adapter with a standard ASUS 40-pin cable on either end would work. However, it was only a novel attempt and the tablet does not recognize the dock as I had hoped.
I am sure Cables-to-Go could get something to work, but I agree that it will be quite expensive. It would be nice if there was a jumper cable accessory to accomplish this same concept since I am in the same position as the OP and typically carry the tablet in its own case and only use the dock when I have alot of typing to do.
On a side note, I did confirm that my Logitech Anywhere Mouse with the Unifying Receiver does work 100% with my tablet and Dock!....I just may be able to leave the laptop at the office yet!
Does anyone have a mapping of the pins and wires? I would like to try and "splice" two cables together to try and make a jumper cable but would need to make sure that I make the right connections. Any assistance would be greatly appreciated.
I don't think that's going to work for several reasons.
First and foremost, if use two TP USB cables as the souce of the parts, you'll end up with a "jumper" cable with male connectors at both ends. You need male to female, remember?
Secondarily (and almost as important) is the number of contacts on the USB end of the cable. USB has four conductors plus shield and nine conductors plus shield in USB 3. Taking a cursory glance at USB plug on my TP cable, that's all there is. I don't see any additional conductors.
Following this, it's EXCEEDINGLY unlikely that the cable has 40 wires (one for each pin on the Prime end) running the full length. If it did, where would they connect to on the USB plug? Kinda silly to include extra copper to go nowhere.
Instead, if you were to pry open the 40 pin male plug, you'll see that most the pins aren't connected to anything. They're not needed for the USB cable.
Sorry to say, this just isn't going to work.
If you do choose to clip one of your cables just to have a look-see, cut the cable somewhere in the middle. If you cut right up next to the USB plug, you won't have ample wire there to repair what you're about to break.
I am aware that you will need a female adapter to make a true "jumper" cable. However, there may be a way of jerry-rigging a connection to the dock if a female connector can't be found (I have yet to find a part online).
My question is more in regards to whether or not anyone had a schematic of which of the pins are connected to which of the respective USB pins so that I could determine the best way of making a connection....short of having a cable for the ASUS TF201 like this: iPhone Extension Cable
Hi,
Someone stepped on my USB cable when it was charging and bent/broke the USB end of the cable (not the end connected directly to my prime), the wires are loose and i'm trying to solder the wires to another USB cable that was lying around.
However i have not succeeded in making this work, probably because im connecting the cables wrong.
Can anyone tell me which wires are supposed to connect to what colours of the usb cable? They're 5 wires in a ASUS USB cable, but 4 in a regular USB cable and not all colours are the same...
Thank you!
Well the Asus cable is a USB 3.0 I believe since it uses up to 15 volts, which means you need another USB 3.0 end to connect to. Other than that I am unsure about the matching of the wires.
Hi,
Does anyone has any idea why the micro-USB connectors which are used to connect a HDMI or VGA cable to the micro-USB port of the Samsung Galaxies are longer than let's say a data micro USB connector?
I've tried a micro-USB extension cable, and they don't work with these video-output connectors because they're too long. When I looked inside the connector I noticed that all the connection points are way down the connector, and that the upper part is just extra. So I've tried filing off the upper part. Now it charges the phone, but still no video output.
Thanks!
Never mind, just found an answer to my question
Apparently the dock / video out connectors are 11 pin micro USB connectors. The data and charging cable connectors are 5 pin.
Now to find an extension cable for that. I wonder if this excists.
It would be much easier to find HDMI/VGA extension cable rather then the 11 ping micro usb.

Indeed, but the problem is that I want to extend the dock connector so I can put my Note 3 next to my dock to put it in landscape.
