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) or ehci(4)
     or xhci(4) must be configured in the kernel.  Additionally, since umass
     uses the SCSI subsystem and sometimes acts as a SCSI device, it requires
     da(4) and scbus(4) to be included in the kernel.

     The umass driver supports USB Mass Storage devices, including:

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).
