Anyone know about a splitter that will take the 30-pin input and let you use one side for the 30-pin power adapter and the other side for 30-pin accessory like USB OTG pigtail?
I'm in the same boat,
Search and search but nothing,
You get USB to 2 30-pin but nothing for 30-pin to 2 30-pin adapters
The only option you have is to buy a Galaxy Tab break out board from Kinetica and solder your own cables to it..
What do you want to use at same time?
It would be nice to run external power while having an accessory plugged in such as the SD or USB drive or keyboard. I have 2 USB keyboards that have the pointing device built into it.
look in m y post in the make your own cables thread.
i added power to the odks circuit board and can watch movies via hdd at same time as charging.
easier way would be use the breaK out board though..
I have the connector parts, just I have to know the pin assignments...

Look at this thread..
Try my post first one before this page..
It explains it..
pin 7 is the posative 5v @2amps...
pin 30 is the earth..
(this is how i run it in car connected to 2 amps 5v source)
works well and if start close to 100 percent battery power leave it plugged in it doesnt drop anything even after watching 4 movies in a row still is 100 percent.
eventually i disconnected it to let the battery drop down alittle as not sure if good to keep it at full charge?
Maybe the best way would be try to follow my dock mod?
that way you can just use the 30 pin usb adapter and add a powered hub.
havent given an update on "line out" output as my usb adapter is covering it up
the outlet socket.might consider opening it up again and finding out if works then relocate the 3.5 stereo socket outlet.maybe could just solder some wires to it inside and add a new output some where else more accessable..

Havent seen that cable before...anybody tried it?
Just curious IF and HOW it works...
I modded my dock to accept charge and host at same time but only triggers charge when hdd is connected whilst power applied.
I've got one from ebay. But its very poor quality. Its functionality is OK, but you cannot charge the Tab. External power is used to power the USB devices. It switches between internal Tab 5V and external 5V when applied. It ok with USB hdd that needs power.
o.k. thanks..
Cant help but wonder about the possibility of using it as charging and host at same time by using different resistor than 20k.not sure if you guys seen the thread about host and charging on galaxy s3 (hw mod) but they discovered a different resistance value 40.2k that could make the power part of the usb travel in both directions at the same time allowing this to happen...
im thinking the same could maybe happen for our 7.7 tab.

Not one to relax and enjoy the spoils of war after conquering the Wall/Car charger mystery I have decided to move on to the subject of USB host without the dock. Sorry if I am duplicating other similar threads but starting a new thread helps me through the process of testing. I'm hoping the asus USB host adapter will be out soon so I can gut it like tuna but till then it is back to the rig I used for the charger probing.
Update 10/16/2011
So what we actually now know.
1. USB host mode requires a board found in the USB Host adapter from Asus
2. Some users are having issues with the adapter staying connected. Bad design IMO, too big of a device to be hanging off the tablet connected to thumb drives and other devices.
3. 5V is being supplied to usb devices, I have not personally verified this but will soon.
Some options
1. Build USB Host "Dongle" with connector and USB adapter.
Sounds like people are having disconnection issues, a dongle might be a better solution for that taking the pressure off the connector on the TF and move it down a wire to dongle connector. This will be my first build since it shouldn't be to difficult.
2. Machine a small attachable dock that sits at the bottom of the TF which contains the host adapter, memory cart reader slots and USB ports.
I love this idea but will take time and money I don't have at the moment. BUT drawings are already done and I'm having my machinist put it on his to do list at the bottom. Prototype in 45 days but no promises.
3. Modding a TF to contain the host adapter internally.
This requires you to open up your TF and install the board and a connector. A daunting task for anyone with even good circuit board and fabrication skills. Best person for this job is Bob, but is there space in the case?

First Mod, Host Adapter dongle.
While building this on I'll looking in to the capability of charging the TF while using the host adapter.
USB adapter shows up tomorrow and I hit the ground running. Pics and updates to come. Stay tuned!
Hey,
Any updates on this? I would love to see a solution to connect USB devices without needing a dock.
Waiting for the official adaptor might take a while: Asus Australia confirmed that the adaptor is not coming any time soon (and maybe never to AUS at all), Asus Germany can't give a specific date.

So what do we know
1. Connecting a USB 2.0 female to female coupler using the factor sync/charge cable from the Table to other USB devices does not work.
2. Asus will be releasing an adapter that allows for USB host features and this tells us it can be done.
3. Asus used some of the usb 3.0 pins to show termination from the tablet to start charging at 15V so this method might be in practice for the usb host function.
I've done a little monitoring of data pins on the factory cable but see no difference between when a device is and is not connected. I have a feeling we are dealing with 2 things, 5v power from the tablet to power the usb device and a pin termination to trigger the host function.

Following the OP's logic..
I do not believe that a Female to Female USB3 would be enough. I suspect and trying to locate one is a pain that you will need not only a USB3 AF to AF but also a USB3 Powered Hub (or USB 3 Powered Device) as the TF cable does not supply power..
I tried the USB 2 AF to AF path with my powered hub and can confirm it does not work, TF will mount fine on PC via the HUB so it is not a connection problem so I suspect like the OP that we need all the magic pins of a USB3 connection which logically would also mean we all the magic of a USB3 hub (or device) as well..
I cannot find a USB3 AF to Micro AF cable anyplace (They are all male) so even if I can get my hands on a USB3 powered hub (which are also rare) I could not complete this experiment..
I suspect the lack of the OP's postings would also indicate they are having the same trouble as well..
So in summary, I strongly believe we need USB3 Powered Hub + USB 3 Cable from the Hub to the TF Cable
Anyone got those?
Well I done some searching and found these two that should provide all the right specifications for the TF but I am starting to have some significant doubts that this is all worth it considering this is only a theoretical solution based on USB3 pins logic vs just pay the $149 price tag and get the keyboard dock that we know will work..

Everithing is said being available in 2-4 days...
Last week was baja 500 prep for my but i'm back and moving forward with testing.
Don't waste your time with the female 3.0 adapter. The tablet is using one of the 40 pins on the proprietary adapter to look for termination from the keyboard dock to activate the USB host function. This is my theory but I still will test all 9 of the 3.0 pins.
The only way I will be able to test all 40 pins on the tablet connector is to either find a bare connector or wait for the asus usb adapter and open it. I'll start lookng for a bare connector next Week

The adapter has shown up in a German online shop (cyberport.de, search for "usb extension kit" or "sd extension kit") and is listed as in Stock. I wrote them an email to get confirmation that they really have it in Stock and shippable. Maybe somebody in Germany can make a teardown and show us the internals!

If you google "1D09-36X" it comes up with other EU sites that carry it. Hopefully it won't be long till we get it in the US.
Does anyone happen to know the type/model/name of the connector is.
Maybe we can find something that is the same pin config and cut it open and splice in a usb 3.0 female cable.
I've spliced many a cable together for similar purposes, just need the connector end.
We as reseller have direct contact with asus. I called today Asus Netherlands about the usb host adapter.
Atm this moment there only 2 accessoires on the market, which are as follow:
- Asus Sleeve
- Asus Dock
The Sales Manager at Asus Netherlands told me that several other people asked for the USB Host adapter also. They said it wont be on the market until 3th quarter of the year (Aug/Sept/Oct).
Asus Taiwain puts these items on the market. Asus Taiwan understands that there is some demand for this USB Adapter.
So, we have to wait until 3th qaurter 2011 or try to fabricate something ourselfs or wait for some crazy chinese which puts something similiar on the market.
The Rezound has a very interesting Micro-USB port that seems to have the outer shape similar to Mini-USB, but with the Micro-USB guts. The cable that comes with the phone has a rectangular plug that seems a bit longer and fits perfectly into the phone's jack. In fact, its amazing... to get the phone connected to it, you have to push the connector in until it 'clicks' into place - very solid.
My wife's DINC suffers from a slutted-out socket that now barely works anymore due to the standard Micro-USB design that seems pretty fragile. Even though a standard Micro-USB fits into the Rezound's unique socket, it doesn't have the solid feel that the OEM version has.
Does anyone know what this newer style connector is called? I would like to find a couple more cables that are longer and feel that by using this type of connector, the Rezound's port should last the life of the phone.
Thanks in advance!!!

It's an MHL plug and there is more info in this thread

Thanks dude...
A normal microUSB cable will still get the job done. It's just put in the reverse as it is on the Incredible. The tabs need to be facing up. I got 3 OEM HTC microUSB cables off ebay for like $7 bucks shipped. And the odd shaped end is probably some proprietary HTC connector, same as they had with the HeroCDMA with the miniUSB.

No, it's a micro-A USB receptacle that supports MHL. There's a difference.
I would rather have the MHL cable... Feels more secure when plugged in..
Has anyone been able to find one on the internet or in store?
Sent from my ADR6425LVW
yeah the security of the MHL cable is worth not using a standard micro USB. for instance when you're using a car charger w/ a standard micro USB, the cable can tug a bit on the connector(depending on length of cable, placement of phone) and cause it to come loose & stop charging... but with the micro A USB(MHL) it's nice & secure and you don't have to worry about that happening.
Anybody have a part number for the OEM cable or best case know where to order it
The really annoying thing about the cable that comes with the phone is that you can't use it with any other micro-A/B USB ports. They seem to have intentionally shipped a cable that you can only use with this device, even though the device itself will take any micro USB plug. Thanks, HTC!

I did say that any other micro USB cable would work on the phone. I have a charger from every blackberry I ever owned, the Inc charger, and a couple miscellaneous cables lying around. It's just that the one that comes with the Rezound now has to go in its own special pile of cables (all by itself) because I can't use it with any other devices. Did not try with the old phone, though. Interesting that you say HTC's physical mods to the micro USB port are the same on the Inc and Rezound, yet the Rezound ships with a proprietary cable and my Inc came with a standard micro USB plug. I'll check when I get home.
it does seem at least that yes, any microUSB cable will work with the Rezound for both charging it and connecting it to your PC.
for the most part, you really only need the MHL support if you plan on going through HDMI out, which you'd then need an MHL/HDMI adapter cable anyway.
the only benefit to the cable that comes with the Rezound is the "snug fit" bit. whereas, it'd be nice if they had a car charger with the exact same micro A USB end to it as i find that all standard micro USB car chargers aren't as snug and depending on phone placement/movement, the connection can get a bit 'loose' and sometime stop charging.
i used to use this motorola car charger but because of how the cable pulled, the connection would constantly come loose unless i used tape to hold it in place.
It's not an MHL port. It's HTC's proprietary ExtMicro-USB port first seen with the HTC Flyer. An MHL port is a standard 5pin Micro-USB A/B port that detects when an MHL adapter is used, and uses those same 5 pins to support HDMI output. If you look at MHL ports on phones like the Evo 4G and Galaxy S II, they are indistinguishable physically from standard Micro-USB B ports. HTC's ExtMicro-USB is compatible with 5pin Micro-USB cables and 5pin MHL adapters. In fact, if you look at the HTC MHL adapter, it's shaped like a standard Micro-USB plug and only has 5 pins. What's different about ExtMicro-USB is that it has some extra pins compared to standard Micro-USB and MHL. I believe it has 6 extra pins, for a total of 11 pins. Those 6 extra pins are not used for MHL, for the reasons stated above. I'm not certain what those pins are used for, but if it's the same as the older ExtUSB (which is compatible with Mini-USB), then those extra pins are used for analog audio output, for use with stereo headsets, etc.

The cable IS for the phone. You can use it to charge and sync. But the PORT can also be used to hookup an MHL adapter for HDMI output. That is IN ADDITION to charging or syncing via USB. The cable that comes with the phone just has a different connector yet is backwards compatable with any regular micro-USB cable.
I'm not sure why this is so confusing to people.
That being said...
Has anyone found a part number or where to buy cables with the non-standard connector?
I have plenty of micro-usb cables, and yes, they do work fine, but I am not confortable with how loose they are. WAY too much play. This especially worries me in the car.

Yea I have been trying to find this too. I was sent the Rezound as a CLNR for my Charge so I didn't even get the original USB cable that comes with the phone when you buy it. Sure the micro-usb cables work, but they feel pretty loose compared to other phones that are designed for micro-usb specifically.
ok guys this is NOT an MHL cable. as said before there is nothing special at all about it besides that it is a snugger fit. any micro usb will work with MHL and you still need the converter.

I know what you mean. I put the part number in and the one that came with the Inc kept coming up. This one looks like it has the same shape as the one that comes with the Rezound.
I made a USB dongle that plugs into the USB port on the touchpad and provides a powered female USB-A port. It is basically a portable USB charger/battery with an OTG cable soldered to the USB port. Attached is a quick pdf showing the process. It's much smaller and more portable than using a y-cable and powered hub or battery pack.
The charger is $13 on Amazon with free prime shipping and OTG cables around $2 on ebay.
It's nice because it's small and I can secure it to the my case with a rubber band, providing a quick connection to a keyboard/mouse or usb flash drive. The particular charger charges via any powered USB port with a provided cable.
This is the battery pack I ordered, note the picture on the amazon page is not 100% accurate:

This hub has 4 ports, a battery plus solar charging. That said, if I buy it I'll probably just plug it directly into the OTG cable rather than solder them together. Then again my soldering can be a little rough.

Deserves sticky, love mods like this even if not always practical.
Cant believe they didnt give the touchpad a powered usb host. I guess they figured people would have issues with not enough power or drain the battery too quick with it.
So I think when I have some spare time I may mod your mod and show how to make a powered usb host that plugs into the wall charger so when your "docking" somewhere to charge you can hook up a keyboard and use it without restriction and even be charging the touchpad at the same time.
Probably don't even need to be too creative a proper Y cable may do the trick out the gate. Just to track one down.
Probably a stupid question, but it wouldn't be my first one...
Could you simply use a USB male-to-male cable to go between the battery pack and the OTG cable? Eliminate the soldering that way?
Or am I missing something?
I found a cable that I think will work perfectly for my idea of doing this from the charger instead of from battery: http://www.dealextreme.com/p/usb-fe...gb-tf-card-card-reader-kit-for-xtc-clip-82289
You can do it much cheaper with adapters and a regular y adapter though, and you may want to do so, so that you can have a longer cable from the charger to the y split, but yeah I will try this out sometime soon and let you know how it works.
The charger probably gives enough power to easily run things like a external HDD and such while the battery pack may not.
@Vicious ... couldn't that possibly put too much power to a USB device? Just saying since it is probably meant to be hooked up to a regular USB 5v port and (I don't know the specifics but) the touchpad USB power adapter has a high AMP output (might be talking sht here).
Nothing to worry about a device only "pulls" the amperage it needs so you can have extra with no harm to the device. It is the voltage that needs to match and usb is standard 5v.
Having too little amperage can actually cause a device harm due to malfunction, like a head crashing on a 2.5" hdd during use or a thumb drive failing to flash properly corrupting a sector.
I feel anybody that uses the touchpad in a docked setting that wants to use a keyboard may very well make use of my idea, that I of course got from the OP's idea.
I'll part it out for the cheapest way to make it without any cutting/soldering and test it soon enough.

That cable will work fine. I wasn't doing anything special, only eliminating the y-cable. I mainly wanted a small form factor way of adding a USB port to my case for portability. Now I can put a movie on a usb drive and watch it on the go.
You generally don't have to worry about using a supply that is to powerful. As long as the voltage output is 5 V, the device will only draw a certain current and consume the corresponding amount of power. The rating on a constant voltage supply is simply the maximum current it can provide, the amount it provides depends on the properties of the device.
Say you have a device, it states it operates at 5 V and draws 100 mA of current. That means the impedance of the device is R = V / I = 50 ohms. So if you use a 5 V supply rated to at least 100 mA, the device will only draw 100 mA. The supply can be rated for 100 mA or 1000 amps, it does not matter. (Although you wouldn't want to use 1000 A source as if something breaks or shorts it can draw a higher current)
Wikipedia "ohms law" if you are not familiar.
I tried to do this but can't get it to work, the touchpad shows the charging battery icon only it's not charging, and running dmesg it say source=charger mA=100 and usb otg exited low power mode and then right after says it entered low power mode... Not sure what the issue is...
edit: I'm thinking it may be my soldering work, gonna give it another pass...

You may have the two data pins shorted together. To the best of my knowledge, this tells the touchpad to go into charging mode. The touchpad charger does this, because in order to charge, it must draw more power than USB ports are designed to provide.
You need to remove the two resistors circled in the PDF. These keep the data pins shorted together as well.
This is a really great idea I think I might try it and your tut is very well explained thanks for taking the time out to put it all together
Thanks
Mouse works fine, keyboard hasn't been tried yet. How do you access a flash drive through this? What are the steps?
If you just cut out the resistors in the battery hub, could you just use the TP's regular cable to plug into one of the ports on the hub?

Curious to find out if this adapter would work on the p6800.. It is said to work with p1000, but i am not sure if it will work with the p6800..
I always have a micro usb cable around for my Galaxy Nexus.. If this works i can leave the proprietary Samsung 30 pin cable home and just carry this small adapter.

Update - The item is no longer on eBay....
I was wondering... We get this 30-pin male to usb male connector... can we use a usb-male to usb-female connector instead of a direct 30-pin to female connector?!
I bought one of these for my 7.7 and it works fine. It ONLY charges. It cannot be used for data.
Search ebay for "Micro USB Laden Dock Adapter" to get another version of the 30 Pin to micro USB Connector. But again: only charging - no transfer

I got one of these. works great for charging through any micro usb charger, even my usb car charger with a micro usb cable plugged into it.
i got one to try then after i made sure it worked ordered 3 more. home, car, office etc etc

I ordered a few of these to work with my older GTs (original, 7 Plus). They've all worked fine with each. I use them with a retractable usb to micro usb cable to lessen the amount of chargers/cables/portable batteries i need to carry (one set will serve my phone and my tablet and just swap out the ends.)
Both work for me also. USB and uSD. Data transfer and video. Haven't tried charging though. Got mine on eBay. Keep an eye out. They'll return I'll bet.

This looks promising
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.
