This is a lot more work than I thought. I had the backend working
perfectly right. But after rebooting, the scanner did constantly hang
after sending the feed command (0x16) and then requesting the extended
status (ESC-f). Has somebody a suggestion what the cause of this may be?
As to the questions of Olaf: I upgraded in two steps, first from from
lenny to squeeze. I compiled iscan-2.29.1 with the epkowa backend 1.0.15
in squeeze. The compilation worked, although some test failed. But the
backend then produced an errormessage which I don't have anymore, but I
think it was the same as on wheezy (see below).
After that I decided just to upgrade to wheezy and check, if the newest
epson2 driver would be working. It didn't. The I recompiled iscan, but
the backend gives the errormessage: "scanimage: open of device epkowa
failed: Access to resource has been denied".
Then I decided to fix the epson2 backend instead of the epkowa backend,
because alread on lenny the epkowa backend didn't work 100% correctly.
Duplex worked fine, but there was a problem when scanning simplex (I
don't remember what it was, but I think it didn't scan the last sheet).
So on lenny I had to switch between 1.0.15 and 1.0.19 of the epkowa
driver for simplex respective duplex, because the 1.0.19 backend failed
I'll try again on the weekend to fix the epson2 driver - I think I miss
just one tiny bit of the puzzle...
