Usually a scanner with a Firewire or IEEE-1394 interface implements
the SBP-2 protocol, which emulates SCSI over IEEE-1394. With an 
SBP-2 device, there is no need for an extra driver, the device
will look and work like a SCSI device. The SBP-2 driver will install
a virtual SCSI controller, and from there on the device can be
accesses by any application that supports SCSI devices. To get
a IEEE-1394 scanner working, you load three modules: ieee1394, ohci1394
(or whatever driver your system requires for your controller) and
sbp2.
