>Description:

   The USB Memorybird (Fujitsu-Siemens) requires a SCSI quirk
   for operation (it doesn't handle 6-byte SCSI read commands).
   FYI, the Memorybird is a small, pen-shaped, battery-less
   flash memory device.  For more information on the hardware:
   http://www.fujitsu-siemens.com/rl/peripherals/homeperipherals/memorybird.html

>How-To-Repeat:

   Connect a Memorybird to the USB port and try to access it.
   You'll get messages like this:

   umass0: BBB reset failed, TIMEOUT
   umass0: BBB bulk-in clear stall failed, TIMEOUT
   umass0: BBB bulk-out clear stall failed, TIMEOUT

   With the patch below attached, everything works perfectly
   fine.
