I have a USB storage device that is probed as follows when inserted:

     umass0 at uhub0 port 1 configuration 1 interface 0
     umass0: Intelligent Stick Intelligent Stick, rev 1.10/1.00, addr 2
     umass0: using SCSI over Bulk-Only

I am wondering how to make use of a umass device as there is no
/dev/umass* device file.  Is there any way to make use of this as a
disk?

Cheers,
Brook
