I have a perfectly working nexus 7, but the only issue is that the USB connector is broken. I was wondering if it would be possible to solder leads onto the micro USB pads or the pads that the micro usb connects to, and then solder a usb otg Y cable onto that? Im looking to set it up as a head unit while still retaining USB OTG support.

For charging only connect to pogo pins, the replacement USB board is easy to install and cheap, $20. Maybe off eBay, been awhile.

The most Micro USB to USB converters are not work if you want to use it for OTG converter, because the 4. pin of the micro usb plug is not connected!
The most ebay and computer shop's converters like this!
If you want to use it for working OTG adapter you have to connect the micro usb connector 4. pin to GND (5. pin).
Like this:
I made this mod on my adapter and it works!
First you have to open up the outter cover and carve the plastic around the micro usb pins. You can use multimeter to check the pinout.
After that solder the 4. pin to 5. pin with a piece of wire.
And finally glue back the outter cover.
Video:
So if you have not working adapter you can mod it, if you have suffice experience with electronic and proper tools.
Only do with your own risk!
I have this Usb converter!
With your mod works perfectly!!
just tried it it works perf, thank you!
Weird I got one off eBay from Hong Kong and it works without Modding. Can open files off a USB stick. Got it for £1

I buy a pair in Dealextreme.com
SKU 50774 o search OTG
It may have a resistor between pin 4 and 5, kind of like a jig,
I remember there was a fun with resistors thread for the sgs1.
I may attack tge free dock I,got from optus.

OTG Cable USB (B) to Micro USB (A) Powered with AAA batteries ?
As one knows, Samsung has promised a MHL Cable
You noticed it is not only a cable but a box out of which you may plug in an extra power supply.
The obvious reason is if the passive monitor does not furnish 5V, the phone will rapidly be out of power.
Now you know that to obtain video rather than anything less, Pin 4 (sense) and 5 (Ground) of micro USB (male A) must be connected with a 365K resistance.
I suppose the dock Samsung is selling for I9100 (yes, I have it) is grounded at 1000K as it provides audio with remote, and yes, the dock provides power supply via extra micro USB as well.
I come to my point: If I want to access any USB data On the Go, I need a cable OTG with 2 ports: USB 2.0/3.0 (female, B sided) to a micro USB (male, A sided, grounded but with no resistance = 0K). Many of them exist on the market out there.
But it is quite impossible to use because of lack of power supply in the passive device (let’s say a handy 1T HDD usually powered via Host connexion !
Would it be possible to insert some sort of receptacle for AAA battery in the middle of such a cable to provide for power while you are for a long time out of access to an electric plug ? Does such a cable exist somewhere to buy ? What would be the sheme to mount this ? HELP !
Is it possible to add USB charging cable to USB-host cable? I want to use mouse\keyboard\flash and charge device in the same time.
I also interested how to add power to USB-host cable for devices "High-power device connected".
OTG and Power
thats excactly my question:
is it possible to use otg cable with a trackball or mouse and at same time charge the S2?
give power to usb mouse and charge S2 over a charger!?
Is it possible to use a game controller over usb otg? Would be pretty nice.
Wanna have a S2Play ;-)

i do have same problem..is there any suggestions to make sgs2 can read the high-power USB flashdisk via otg??
An USB hub with external power maybe ? I didn't tried this kind of setup, but it should work. I have a hub, but I don't have a OTG cable yet.

I've been try this, but still doesn't work for me..I'm also used electrical multi-tester, and the usb flash already has 5V voltage but in my sgs2 still nothing happen (my usb flashdisk doesn't mounted to sgs2)..
Is there any driver/apps do I need to install first before using OTG?? or, is there two kind of sgs2, the one which support OTG and the other one not??
please someone help me...One point I choose this SGS2 is the OTG feature..
PS: sorry for my english
I bought these on ebay. The HDMI is short but worked but when I connect both cables to lapdock, the USB is not being recognized so the keyboard/mouse is not working. I want this just to act as an extension so I can use full lapdock abilities with cables. Any idea what's going on (cable charges on plug but does not charge on lapdock)? Maybe someone has better usb cables.

From your title I've been looking for these (or similar) cables for a long time and have been unsuccessful. However I have yet to try them.

i don't think it will work either way, tried a few things like this with no avail.
why wouldn't they? Cheap build quality that doesn't include the data wires? Hell I'll be willing to splice two cables together to get our desired effect, the only problem is that cords with a female micro usb are incredibly hard to come by
So that is what you think it is? No data on the usb cables.

the only reason that is my suspicion is because there are many "charging" products out there that don't really need data. Why there would be a need for such a small charging extension cable is beyond me, but it's the only solution I can think of, but I have no way of confirming or denying it either. The ebay descriptions seem to imply that the data wires are there, but we all know how reliable ebay can be...
Another idea I had was that it might be sensing the resistance in the cable, since, if I remember correctly, that was how some think/though the car dock puts the atrix into car mode without a magnet as is/was commonly used. Again these are just ideas.
Or the cable is just so poorly made that it's defective...I honestly have no clue
Has anyone got full lapdock capabilities using extension cables? I can only get the screen working and not the mouse and keyboard.
The HDMI extender was the hard one to find. There are other micro USB extenders out there, theoretically with all wires connected....
http://www.usbfirewire.com/uextendmicrob.html
Kind of makes me wish i hadn't hacked up my lapdock to work with the Otterbox
Where did you get your HDMI extender? I got mine from All4Cellular but it's quite short. Will have to get another HDMI one if the usb cable you recommended works.

before I read that post, I was looking around the forums and the web yesterday well into the night. here are some of the things I've found that might be relevant to everyone (and it might possibly be cheaper, though more diy).
Micro USB stuff:

then the hdmi cable that came with our phone:

The HDMI certainly looks like it may work but the reason I didn't buy that product from ebay a few weeks ago was because it was $50. Now miraculously, it's only $6. Maybe I'll get that if the USB cable I just bought that was suggested works a few posts back.

This micro usb extension cord explicitly states that all 5 wires are connected (compatible with droid bionic for the purpose of docking with a case on the phone):

The HDMI cable seems to work. On the lapdock, with just the HDMI cable hooked up, it functions like it was it's an entertainment center.
The USB cord will need to be modified a little bit. I can't get it to seat right on the USB jack of the dock. I'll need to shave it down a bit as it doesn't sit down snugly.

I ordered the USB cable and experience this same problem, though I am waiting for my hdmi parts to come in (by April 6th I should have all my parts...). The cable itself works flawlessly as a micro usb extension cable when connecting it to the computer.
again as mentioned in the other thread, you want to be careful with the 5v coming out that micro hdmi port. for connecting back to your phone would be no issue, as the phone charges using this voltage, but hooking the lapdocks micro usb up to a host device probably wont appreciate the 5v coming back up the cable, where normally the usb device would be pulling power from said host, not providing it.
one suggestion is to just clip the red wire inside your micro usb cable/adapter.
btw the adapters i use do fit snugly side by side, without modification.
I've been following this thread for a little while now, and I wanted to share something I found.
I was looking at the Motorola Travel Webtop adapter. And I was curious to see whether it could be tweaked to suite our needs. I naively thought/hoped that I could flip the connectors in the device to make a small adapter to connect the Atrix to newer Lapdocks. Unfortunately as you can see in the pictures below (sorry not enough posts to link to the pictures) the two connectors are connected via a PCB not wires or a ribbon cable. Although I still have high hopes that I can de-solder the HDMI and USB connectors, and use a small length of flat ribbon cable to connect them and then re-positions the connectors in the case, to build a micro adapter to use the Atrix on the newer Lapdocks. Should this fail this will at least prevent others from making the same mistake, and solve the mystery of what's really inside the Webtop Travel adapter.
Do any one know if this Micro HDMI Cable would work for Lapdock.

Description says for Asus tf201 MEMO ME171.
I believe all Cables are standard. Can this used to Atrix 4g with Lapdock?
I have otterbox case for Atrix and don't want to Remove cover everytime to plug in Lapdock.
Hi. I was just wondering is it safe to use a micro usb cable that is tight on the port? I bought a 3rd party usb otg cable since oem ones weren't available. It works fine but the micro usb end fits so tightly into the port of my note. It takes a bit of force to pull it out. Is that fine or will it eventually damage the port? Funny thing is when I use the cable on my dad's HTC or my mom's blackberry the micro usb cable seems to fit fine and not tight.

So I had installed a 2012 Nexus 7 in my car dash. That went relatively easy since you could just move the ribbon cable for the charge port and plug almost any cable into it. I have it apart and decided to upgrade to the 2013 version. The problem is the screen is attached to the same board the Micro usb port is soldered to and I have almost no room on the side of the tablet. It being a Hair taller is killing me. Does anyone know where I can get a very low profile micro usb cable? Something similar to what is attached to this charger. Need it to have data as well. Or if anyone has any ideas on what could be done I'd like to hear.

I want to use 90 ° micro usb cable, that would not fit?
An Idea
The board with the micro USB can easily be removed with a small screwdriver so it would just hang behind the nexus inside the car. That's no good if you plan on using the nexus like a regular tablet.
So I recently bought a magnetic cable adopter, It has two parts an android micro usb head and the body where it can connect to the usb head with the use of magnet and the other side is a micro usb port the body also has a led indicator.
Given that my phone is usb otg capable, when I connect my usb to the micro usb port at the body of adopter my phone can't read it.
Is this a hardware problem where the magnetic adopter is not capable of reading other devices eg. Usb, mouse, keyboard etc. and only supports charging?
Or can I still use the usb otg features by using a 'usb otg cable Y'?
Or is there other way?
Sadly I can't try usb otg Y since I haven't bought any and want to make sure it will work before I buy.
Feel free to ask more information if it's not sufficient enough. Thanks!
OTG + Magnetic cable
Same problem but at least I know that OTG can (should?) work through a magnetic cable as I have another device on which it does.
