I've commited a new umass(4) driver for USB mass storage devices.
It's a port of the new FreeBSD driver and it works much better (for
me) than the old one.  Apart from working better it also supports ATAPI
devices as well as SCSI devices so more hardware should be usable now.

I've tried the driver with a Zip 100 and an Imation Superdisk.  If you try it
with something else please tell me what happens.
