Hi,

I've come across a problem with an IOMEGA CDRW86522EXT USB cd writer. I'v=
e got=20
2 machines, 1 with just a single IDE harddrive, the other with 1 IDE driv=
e=20
and 3 SCSI harddrives. Both machines are running NetBSD 1.6.2_STABLE The=20
writer works fine on the machine with the single IDE drive, but the machi=
ne=20
with the SCSI disks however doesn't get to attaching umass to scsibus.

Box with 1 IDE hardrive on which the writer works:

# dmesg

Box with the SCSI disks on which the writer doesn't work:

I assumed I'd see something like:

umass0 at uhub3 port 2 configuration 1 interface 0
umass0: IOMEGA CDRW86522EXT3-B, rev 2.00/0.02, addr 2
umass0: using SCSI over Bulk-Only

cd0 at scsibus3 target 1 lun 0: <IOMEGA, CDRW86522EXT3-B, QOP3> SCSI0 5/c=
drom=20
removable


Can anyone shed some light on this problem?

Thanks!
