My system is a slackware9.0 distribution running kernel 2.4.21-pre7-ac1.
I have a usb2 enclosure that previously had a hard disk in it that
worked ok (modules correct, etc.). I replaced the hard disk with an
adaptec cd-r and that device is now not recognized by my system. (It
worked ok when it was directly attached to the motherboard.)

cdrecord -scanbus gives:
cdrecord: No such file or directory. Cannot open '/dev/pg*'. Cannot open
SCSI driver.

Relavant output from lsmod is:

ide-scsi               10352   0
sg                     28396   0  (unused)
scanner                10392   0  (unused)
usb-storage            24912   0
sd_mod                 11020   0  (unused)
ehci-hcd               17320   0  (unused)
usb-uhci               23372   0  (unused)
usbcore                63104   0  [scanner usb-storage ehci-hcd
usb-uhci]
scsi_mod               57524   4  [ide-scsi sg usb-storage sd_mod]
loop                    9624   0  (unused)


Any help would be appreciated.

Most likely it's a hardware issue-many of the USB/firewire > IDE bridges are
either ATA (Hard Drives) or ATAPI (most everything else) but not both.
