     The umass driver provides support for Mass Storage devices that attach to
     the USB port.  Supported are:

     The driver also supports some USB adapters for removable media.  Among
     the supported models are:

     SanDisk SDDR-31 (Compact Flash)
     SanDisk SDDR-75 (only Compact Flash port works)

     Last but not least, support for SCSI drives, da.

EXAMPLES    [Toc]    [Back]

	   device umass
	   device scbus
	   device da
	   device pass

     Add the umass driver to the kernel.

	   camcontrol rescan 0

     Rescan a Zip drive that was added after boot.  The command above assumes
     that the Zip drive is on the first SCSI bus in the system.

	   camcontrol rescan 0:0:0
	   camcontrol rescan 0:0:1
	   camcontrol rescan 0:0:2
	   camcontrol rescan 0:0:3

     Rescan all slots on a multi-slot flash reader, where the slots map to
     separate LUNs on a single SCSI ID.  Typically only the first slot will be
     enabled at boot time.  Again, this assumes that the flash reader is the
     first SCSI bus in the system.

	   bsdlabel -w da0 zip100
	   newfs da0c
	   mount -t ufs /dev/da0c /mnt

     Write a disklabel to the Zip drive (see vpo for the disktab entry), creates
 the file system and mounts the new file system on /mnt.

	   newfs_msdos /dev/da0

     Create a new FAT type file system.
