It seems atapicam detects this cdw device ok (from dmesg):
cd0 at ata1 bus 0 scbus1 target 0 lun 0
cd0: <TSSTcorp CDW/DVD TS-H492C SI00> Removable CD-ROM SCSI-0 device
cd0: 16.000MB/s transfers
cd0: cd present [1 x 2048 byte records]
but scanbus fails:
# cdrecord -scanbus

hilling
cdrecord: Error 0. Cannot open SCSI driver.
cdrecord: For possible targets try 'cdrecord -scanbus'.
cdrecord: For possible transport specifiers try 'cdrecord dev=help'.
#
I think cdrecord -scanbus should work even if there is no cdw device
present. For example this is what I get on ia64 9.0-current:
# cdrecord -scanbus

Using libscg version 'schily-0.8'.

So I think this Cannot open SCSI driver error might be
caused by some other problem on my system, and not by
the cdw device. But where??
many thanks
