Are you still using the same USB A male to USB A male cable that you suspected of having troubles earlier? If so, one of the pins might be making poor contact at the RasPi A port. Try both RasPi A ports -- sometimes one is out of spec while the other isn't.Fox0 wrote:The Lapdock Keyboad/Touchpad works now all the time with my PC (running Win8 atm) but still doesn't work with the Pi (tried raspbian and raspbmc today). The Pi works with every other USB Device i have, i'll even tried another Pi... i have absolutely no clue what the problem is.
Have you tried having your RasPi talk to a USB device (say a keyboard or mouse) through the same cable+adapter you use between the Atrix Micro USB plug and RasPi's port A? This is to make sure the cable+adapter works when plugged into a RasPi A port. You'll need an additional Micro USB male to USB A female cable+adapter.
