NAME
     sbp -- Serial Bus Protocol 2 (SBP-2) Mass Storage Devices driver

SYNOPSIS
     kldload firewire
     kldload cam
     kldload sbp

     or

     device sbp
     device firewire
     device scbus
     device da
     device cd
     device pass

DESCRIPTION
     The  sbp  driver  provides  support  for  SBP-2  devices that attach to the
     firewire (IEEE 1394) port.  It should work with  SBP-2  devices  which  CAM
     layer supports, for example, HDD, CDROM drive and DVD drive.

     Some  users  familier  with umass(4) might wander why the device is not de-
     tached at the CAM layer when the device is unplugged. It's detached only if
     the device has not been plugged again during several bus  resets.	This  is
     for  preventing  to detach an active filesystem even when the device cannot
     be probe correctly for some reason after a bus reset or when the device  is
     temporary	disconnected  because  the user changes the bus topology. If you
     want to force to detach the device, run 'fwcontrol -r' several times.
