Could we have a few bug reports to try to diagnose, please?
I tested sbp2 with the logic as presently in 2.6.13-rc2 and added printks everywhere where linux1394.org's old code would do a conversion. The result: DViCO Momobay FX-3A 3.5" HDD, based on TSB42AA9A bridge ------------------------------------------------------- Jul 10 18:30:15 shuttle kernel: scsi0 : SCSI emulation for IEEE-1394 SBP-2 Devices Jul 10 18:30:15 shuttle kernel: ieee1394: sbp2: Node 1-00:1023: Using 36byte inquiry workaround Jul 10 18:30:16 shuttle kernel: ieee1394: sbp2: Logged into SBP-2 device Jul 10 18:30:17 shuttle kernel: ieee1394: sbp2: sbp2_check_sbp2_response: case INQUIRY, TYPE_RBC Jul 10 18:30:17 shuttle kernel: Vendor: DViCO Model: MOMOBAY FX-3A Rev: REV1 Jul 10 18:30:17 shuttle kernel: Type: Unknown ANSI SCSI revision: 02 Then silence. $ cat /sys/bus/scsi/devices/*/type 14 Side note: The FX-3A does not really need the inquiry workaround. It is just matched like a Momobay CX-1 in sbp2's workarounds section. But the inquiry hack is harmless when applied on the FX-3A.

More data from other devices including CD-RWs (and from FX-3A without inquiry hack) will follow later.
