Why on the SCSI level?  I would expect the usb-storage level to be more 
appropriate.  We can add an unusual_devs entry with the
US_FL_IGNORE_DEVICE flag.

Or do you mean to create a flag merely telling the SCSI layer not to
issue resets for this device?  That won't work; the reset in question
was initiated directly by usb-storage, not by the SCSI layer.
