This is true. This scanner has ports for both SCSI and USB.

When I launch "Yast2 > Hardware > Scanner", in the "Autodetected
Scanners" box I'm shown "USB Scanner (vendor=0x05da, product=0x20b0) at
libusb:002:002". This, after making the changes already mentioned in
this thread.

When I then click on "Configure" I'm given the list of drivers
(="backends"?) and select the one for Microtek X12USL. Clicking on
"Next", the next panel shows that "microtek2" as an "Active Driver", but
lists no "Active Scanner". Telling me the same thing as "scanimage -L".

Well that's true now. :) Seriously, you may well be right. I wouldn't
come to that conclusion on the basis of a webpage alone. It's often the
case, especially with Linux, that documents and webpages don't reflect
the lastest capabilities. Even in the paid, commercial world, writing
up the documentation is pretty much an afterthought, far lower down the
long list of priorities than providing technical functionality.

It's also the case that, as I understand it, scsi modules are required
for this to work. I haven't read the code, but isn't the scanner's
USB output is read by the USB drivers and this handed off to scsi
drivers? Maybe you can describe better the role of the scsi modules in
getting this scanner to work....


Johannes, one part of the documentation I didn't understand concerned
the libraries (found in /usr/lib/sane/). Perhaps you could clarify what
needs to be done there and how to ensure it's been done (correctly).


Thanks very much for your responses.


Best regards,
ken
