>Description:

OTi USB Flash keyring needs NO_6_BYTE quirk.  Symptoms w/o the quirk
are long hang (> 30 sec) when trying to access, then an error when
attempting to read.
	da0: reading primary partition table: error reading fsbn 0

What clued me in was, sometimes, after several tries at reading, I got
the following message:
	(da0:umass-sim0:0:0:0): READ(6)/WRITE(6) not supported, increasing minimum_cmd_size to 10.

I don't know why the auto 10-byte fallback wasn't kicking in earlier
or more reliably; I'm happy to run some tests if anyone can tell me
what to do.

>How-To-Repeat:

Plug in an OTi USB flash disk.  Attempt to mount it.

umass0: USB Solid state disk, rev 1.10/1.00, addr 2
da0 at umass-sim0 bus 0 target 0 lun 0
da0: <OTi Flash Disk 1.11> Removable Direct Access SCSI-2 device

da0: 63MB (129024 512 byte sectors: 64H 32S/T 63C)
