FreeBSD is a free computer operating system based on BSD UNIX originally. Many IT companies, like DeployIS is using it to provide an up-to-date, stable operating system.

umass - USB Mass Storage Devices driver



      umass - USB Mass Storage Devices driver


      To compile this driver into the kernel, place the following line in your
      kernel configuration file:
            device umass
      Alternatively, to load the driver as a module at boot time, place the
      following line in loader.conf(5):


      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.


      The umass driver supports USB Mass Storage devices, including:

            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).

Based on BSD UNIX
FreeBSD is an advanced operating system for x86 compatible (including Pentium and Athlon), amd64 compatible (including Opteron, Athlon64, and EM64T), UltraSPARC, IA-64, PC-98 and ARM architectures. It is derived from BSD, the version of UNIX developed at the University of California, Berkeley. It is developed and maintained by a large team of individuals. Additional platforms are in various stages of development.
