Ahh, that wouldn't work at all. The "__test_and_set_bit()" thing isn't
atomic at all, and no amount of memory barriers around it would he

What happens is, there's a nice little LED on the Cruzer stick,
that is "lit" when the stick itself is not in a "power suspend" state

You don't need the "smp_mb__before_clear_bit()" there.
The regular "clear_bit()"

Oh, nice. The usb-storage (SCSI) disk spins itself down and we can't handle
that.
Should we be disabling auto-spindown when we connect the device, or be able to
handle this by sending the start command when needed

users include stex (promise supertrak thingy) and qla2xxx. The former at
least has reported bugs in this area, not sure why we haven't seen any
for the latter. It could be because the window is narrow and that other
condition
