# NAME

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

# SYNOPSIS

`sbp* at ieee1394if? euihi ? euilo ?`

# DESCRIPTION

The `sbp` driver provides support for SBP-2 devices that attach to the IEEE1394 port. It should work with all SBP-2 devices which the scsi(4) 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 scsi(4) 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 `fwctl -r` several times.
