> Could you check this with the Rock-box developers first!

The bug was in Rockbox indeed. It turns out that the Rockbox USB stack 
was expecting to receive a reset command as part of the USB 
initialization sequence. Linux, Windows and OS X all issue one. FreeBSD 
does not. Hence, Rockbox was misbehaving under FreeBSD only. I made a 
patch [1] that I hope will be committed soon.
