Pretty sure I've got this post in the right place.

Did a little research on adding external USB keyboards to Android devices, and came up with with a step by step guide on rigging a setup to use any usb device (I believe it's stated anything that works with linux) with an android phone. The problem here is this is specified for the Motorola Droid. Anybody know if this would work with the backflip either pre or post update to 2.1?
