39 .Nd Serial Bus Protocol 2 (SBP-2) Mass Storage Devices driver
41 .Cd "kldload firewire"
56 driver provides support for SBP-2 devices that attach to the FireWire
58 It should work with SBP-2 devices which the CAM layer supports, for example,
59 HDDs, CDROM drives and DVD drives.
61 Some users familiar with
63 might wonder why the device is not detached at the CAM layer when the device
65 It is detached only if the device has not been plugged again
66 during several bus resets.
67 This is for preventing to detach an active file system
68 even when the device cannot be probed correctly for some reason after a bus reset
69 or when the device is temporary disconnected because the user changes the bus
71 If you want to force to detach the device, run
73 several times or set hw.firewire.hold_count=0 by
76 Some (broken) HDDs do not work well with tagged queuing.
77 If you have problems with such drives, try
78 .Dq Nm camcontrol [device id] tags -N 1
79 to disable tagged queuing.
