USB drive is a Pioneer DVR-SK11B-J. It's reported as ...

scsi0 : SCSI emulation for USB Mass Storage devices
Vendor: PIONEER Model: DVD-RW DVR-K11 Rev: 1.00
Type: CD-ROM ANSI SCSI revision: 02

I've tried at least 2 other USB drives (Plextor PX-208U, and Sony CRX85U),
and both of these drives also exhibit the same problem.
