Two that I have right here yield 0 80 2 2 20 0 0 0 and
0 80 0 2 1F 0 0 0, respectively. (All in hex.)

The 20 in the first is a bug - the INQUIRY gives only 36 bytes.

You do not make me happy with wonderful SCSI patches right now.
I like to go slowly.

[I did introduce this use_10_for_ms; it allows a very large
cleanup in the usb-storage code. Submitted the SCSI part of
the patch and waited for it to be applied. That took a while
and when it went in I was a bit short on Linux time. So Matt
got impatient and started doing the rest himself. He patched
sr.c - something I would not have done, I considered the SCSI
part settled - perhaps things broke a bit but James went in and
fixed some things again. So maybe we are now again ready for
the intended large cleanup. I would like to see that done,
and afterwards see this area stable for a few kernel versions.]
