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 the
       CAM layer supports, for example,	HDDs, CDROM drives and DVD drives.

       Some users familiar with	umass(4) might wonder why the  device  is  not
       detached	at the CAM layer when the device is unplugged.	It is detached
       only  if	 the  device has not been plugged again	during several bus re-
       sets.  This is for preventing to	detach an active file system even when
       the device cannot be probed 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.

       Some (broken) HDDs do not work well with	tagged queuing.	 If  you  have
       problems	 with  such  drives, try "camcontrol [device id] tags -N 1" to
       disable tagged queuing.
