Hi,

It means a USB kernel device driver did not detach. Historically there 
has been several issues in cam/scsi where detaching the instance hangs.

Try running kgdb and backtrace all USB process treads. Look for "detach" 
keyword.

I've been thinking to maybe catch signals during the sx locking so that 
usbconfig can be CTRL-C'ed.
