Hi,
I have a KW-21CS SmartMedia/Compact Flash reader which identifies
itself as a "ScanLogic SSFDC-CF 0.74". This device reports a SCSI
revision of 1 for all its devices, which is wrong according to the USB
storage specs. The revision is fixed up in protocol.c, but it ends up
as SCSI revision 3 which messes up the LUN handling in other parts of
the kernel. The following change fixes this problem for me, and I
think it belongs in the mainstream USB code too.
