I answered that question once already but forgot to Cc the list.

I gave that a whirl but it didn't work.  Seems like camcontrol isn't
able to send raw commands to the umass disk through the USB stack.

Here's the output:

camcontrol idle da0 -t 5
(pass4:umass-sim0:0:0:0): IDLE. ACB: e3 00 00 00 00 40 00 00 00 00 01 00
(pass4:umass-sim0:0:0:0): CAM status: Function Not Available

The disk doesn't spin down.
