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

NAME
     umass -- USB Mass Storage Devices driver

SYNOPSIS
     device umass

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

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 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.  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).
