Are there any known issues with the umass driver that
makes things _extremely_ ( < 300kb/sec) slow for this
USB 2.0 hard drive below? Perhaps this needs some
sort of quirk entry in umass_quirks.c?
umass0 at uhub0 port 2 configuration 1 interface 0
umass0: BUSlink USB 2.0 Hard Drive, rev 2.00/0.01,
addr 2
umass0: using SCSI over Bulk-Only
scsibus0 at umass0: 2 targets, 1 luns per target
scsibus0: waiting 2 seconds for devices to settle...
sd0 at scsibus0 target 1 lun 0: <SAMSUNG, SP8004H,
QW10> SCSI0 0/direct fixed
sd0: could not mode sense (4/5); using fictitious
