Ah, the Bruce Schneier blog comments have the very valuable comment:

   The removable media device setting is a flag contained within the
SCSI Inquiry 
   Data response to the SCSI Inquiry command. Bit 7 of byte 1 (indexed
from 0) is 
   the Removable Media Bit (RMB). A RMB set to zero indicates that the
device is not 
   a removable media device. A RMB of one indicates that the device is a
removable 
   media device. Drivers obtain this information by using the
StorageDeviceProperty 
   request.

So U3 is a different hardware spec, and U3 function can't be copied to
non-U3 media.  That's good.  But the remarks about custom USB hardware
there make me want to reach for the ol' glue gun! Of course, the real
problem is still failure to adhere to least privilege.

Thanks for the link, Bill.
