Please remove the Minolta Scan Dual. It needs a special driver as it uses
SCSI over USB.
Your disconnect_scanner() is racing with read, write and open.
You need to take the BKL not only in open, but in disconnect and close, too.
Then you make the freeing of memory in disconnect conditional on the flag you
set at open time. If it is not set you set a new flag to be added which would
cause close to do what disconnect would do. You may also check this flag at
the beginning of read and write to quickly return ENODEV.
