+.Sh NAME
+.Nm sbp
+.Nd Serial Bus Protocol 2 (SBP-2) Mass Storage Devices driver
+.Sh SYNOPSIS

+.Cd "kldload sbp"
+.Pp
+or

+.Cd "device sbp"
+.Cd "device firewire"

+.Cd "device da"
+.Cd "device cd"
+.Cd "device pass"
+.Sh DESCRIPTION
+The
+.Nm
+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.
+.Pp
+Some users familiar with
+.Xr 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 resets.
+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
+.Dq Nm fwcontrol Fl r
+several times or set hw.firewire.hold_count=0 by
+.Xr sysctl 8 .
+.Pp
+Some (broken) HDDs do not work well with tagged queuing.
+If you have problems with such drives, try
+.Dq Nm camcontrol [device id] tags -N 1
+to disable tagged queuing.
