     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:

     IBM 256MB USB Drive(MSYSTEM DiskOnKey2)
     Iomega USB	Zip 100	drive
     Iomega USB	Zip 250	drive
     Logitec LDR-H443U2	DVD-RAM/-R/+R/-RW/+RW Drive
     Microtech International, Inc. USB-SCSI-HD 50 USB to SCSI cable
     Panasonic ("Matshita FDD CF-VFDU03")
     Panasonic KXL-CB20AN Portable DVD-ROM/CD-R/RW
     Panasonic KXL-CB35AN(DVD-ROM & CD-R/RW)
     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:

     PNY Attache Flash Drive
     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(4) and	one of uhci(4) or ohci(4) must be configured in	the kernel as
     well.  Last but not least,	support	for SCSI drives, da(4).

	   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(4) for	the disktab(5) entry),
     creates the file system and mounts	the new	file system on /mnt.

	   newfs_msdos /dev/da0

     Create a new FAT type file	system.	 Care should be	taken not to run
     newfs(8) on devices that already contain data, as this will result	in the
     information being lost.

     Many consumer devices such	as digital cameras automatically create	MS-DOS
     based file	systems	when storing information such as images	and videos.
     These file	systems	can be accessed	by specifying the file system type as
     msdos when	using mount(8).

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