     umass -- USB Mass Storage Devices driver

     device umass

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

     Iomega USB	Zip 100	drive
     Iomega USB	Zip 250	drive
     Microtech International, Inc. USB-SCSI-HD 50 USB to SCSI cable
     Panasonic ("Matshita FDD CF-VFDU03")
     Trek Thumbdrive 8MB
     VAIO floppy drive (includes Y-E Data Flashbuster-U)

     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)
     Sitecom CN-300 MultiFlash (MMC/SD,	SmartMedia, CF,	MemoryStick)

     Among the supported digital cameras are:

     Asahi Optical (PENTAX) Optio 230 &	330

     usb and one of uhci or ohci must be configured in the kernel as well.
     Last but not least, support for SCSI drives, da.

	   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), cre-
     ates the file system and mounts the new file system on /mnt.

	   newfs_msdos /dev/da0

     Create a new FAT type file	system.

     ohci(4), uhci(4), usb(4), vpo(4), disktab(5), camcontrol(8), bsdlabel(8)
