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.

Note that umass(4) does not detach the device from the CAM layer when the device is unplugged. The idea is to prevent detachment of active filesystems due to temporary disconnects or changes in the bus topology. You may have to run “fwcontrol -r” several times for the system to properly detach such devices.

Some (broken) HDDs don't work well with tagged queuing. If you have problems with such drives, try “camcontrol [device id] tags -N 1” to disable tagged queuing.
