Excellent advice Richard. This enabled me to fix support for Creative
Nomad Muvo mp3 player which also is an umass BBB device.

The main problem with it was that it didn't like the PREVENT ALLOW command,
which isn't covered by any quirk.

A patch for this device is now available at
http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/53094.

Thanks!
