Raspberry Pi and Motorola Lapdock






Here's some info for those interested in setting up a Motorola Lapdock to work with the Raspberry Pi.  This is extremely easy to set up and should work without the need for any hardware modifications.  I used the Atrix Lapdock, which can be found between $50 and $100 on various websites.  I used the Debian Squeeze image from the Raspberry Pi downloads section.  I haven't had luck with Arch Linux ARM.




Parts List

~Raspberry Pi
~Motorola Lapdock (Atrix works)
~1 USB Male to Micro USB Male cable (Standard cell phone cable)
~1 USB 2.0 A female to Micro USB B female adapter cable FF
~1 Micro HDMI Type D Female to Micro HDMI Type D ~Female Connector Adapter Gold
~1 USB Male to USB Male cable  *You will need to open this cable and cut the red 5 volt wire*
~1 MICRO HDMI to HDMI cable


*Please note, my Micro USB and Micro HDMI ports are reversed on my Lapdock due to a previous modification unrelated to the Raspberry Pi.  Yours should work out of the box, without any modifications to the Lapdock.

Wifi
I used a Netgear wg111v2 adapter plugged into one of the Lapdock's USB ports.  I used this guide as a reference, but obviously my adapter is different.  The Debian Squeeze image has the drivers for the wg111v2 adapter preinstalled.
