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.

fixed the link:

links appear to be broken...

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.

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.

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.

The HDMI extender was the hard one to find. There are other micro USB extenders out there, theoretically with all wires connected....

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:

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):

I bought the HDMI extension cable and the USB cable above. I have a lapdock so I'll post if it works.

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.
