UMASS(4)	       FreeBSD Kernel Interfaces Manual		      UMASS(4)

NAME
     umass -- USB Mass Storage Devices driver

SYNOPSIS
     To	compile	this driver into the kernel, place the following line in your
     kernel configuration file:

	   device scbus
	   device usb
	   device umass

     Alternatively, to load the	driver as a module at boot time, place the
     following line in loader.conf(5):

	   umass_load="YES"

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

     To	use the	umass driver, usb(4) and one of	uhci(4)	or ohci(4) must	be
     configured	in the kernel.	Additionally, since umass uses the SCSI	sub-
     system and	sometimes acts as a SCSI device, it requires da(4) and
     scbus(4) to be included in	the kernel.

EXAMPLES
	   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
     msdosfs when using	mount(8).
