Transparency adapter for UMAX 1220S

Having now acquired a transparency adapter for my UMAX 1220S scanner, I would
like to be able to use it with SANE as well as the flatbed scanner part, but
I seem to have run into some problems. Not being able to find anything in the
sane-develop archives I am turning to the list. If I did in fact overlook
something, please feel free to tell me where it is in the language of your
choice :-)

My problem may not be SANE, but the Linux kernel that I am using (2.1.125),
however, I suspect that you guys on this list may have more knowledge about
this particular issue than the linux-kernel folks.

When I do not connect the transparency adapter to the scanner everything seems
to work fine (mostly) and I can scan pictures to my hearts content, but when I
connect the transparency adapter and reboot Linux (I don't know if I have to do
this, but it is just to be sure) the scanner is not recognized at all. Nothing
appears in /proc/scsi/scsi, nor is find-scanner able to detect it.

I know my Linux kernel is a development version, so that might have some
influence, but almost all kernels since 2.1.119 have behaved very well for me
for everything else I do. I just got the transparency adapter and have only
tried it with the latest kernel.

My SCSI card is an Adaptec 1542B and SANE is the latest 0.74. My Linux distribu-
tion is Slackware (I think it was 3.0) updated to compile and run the latest
kernels.

Has anyone here any experience with the transparency adapter for UMAX scanners
especially 1220S of course, because then I would very much appreciate your
advice? The SANE documerntation briefly mentions the transparency adapter, but
when I for example run xscanimage, that option doesn't exist (even as a greyed
out non-selectable option) so I wonder if it has in fact been tested?

Thank you very much for your time,

Peter
