Rockbox on a USB device causes kernel panic on 7.0

The Rockbox USB code keeps changing with each build - it used to request 
power (using its own USB stack) until very recently for me, but as of a 
couple of days ago, reboots into the original firmware again.

It will be difficult to debug the FreeBSD side of things when the 
Rockbox code is so volatile and fragile.
