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

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