Here is my experience with keyboards on Beagleboard. 1. Make sure the USB hub has external power (I'm not 100% sure this is a requirement). 2. Make sure the keyboard is plugged in before the BeagleBoard is turned on. 3. Make sure the keyboard is simple. My fancy ergonomic keyboard will not work with Android, but my $7 simple keyboard does work.
