The scsi ... format is quite independent from the format of the actual
device file names. It's described in man sane-scsi. The third argument
is the type of the device and "Scanner" looks right :-)

One guess: It looks like the OS/2 code simulates a Linux
/proc/scsi/scsi file by creating a temporary file. However, the format
doesn't seem to completely match. E.g. The "Type: Scanner" entry is
missing. This is probably the reason for your observation.

Here is an example of the output of /proc/scsi/scsi:

Attached devices: 
Host: scsi0 Channel: 00 Id: 06 Lun: 00
  Vendor: MUSTEK   Model: MSF-06000SP      Rev: 3.12
    Type:   Scanner                          ANSI SCSI revision: 01
    
Maybe you can fix the code in sanei_scsi.c around line 677 or the
detection around line 3479? I don't know if you can get the Type:
information from OS/2. If you can't, maybe just add a fixed "Type:
Scanner"?

Patches welcome :-)

Bye,
