Dear all,
I never really succeed to use this scanner when I purchased it some
years ago, but I wanted to give it a last try. Please don't suggest to
use it in a windows VM, it brings me out in hives.
$ lsusb
Bus 001 Device 027: ID 055f:040b Mustek Systems, Inc. ScanExpress A3 USB
1200 PRO
It seems different from the Mustek ScanExpress A3 USB (usb 0x055f
0x0210) supported by the gt86xx backend. I suspect it is only USB1.0. I
tried to override it with my modelid, created a dir
/usr/share/sane/gt86xx, added the firmware a32fw.usb, but it fails when
I try scanimage (a32fw.usb, error message : open of device gt68xx
[vendor & dev id] failed Invalid argument).
Then I got another idea, as other posts suggest that my scanner I
related to Mustek BearPaw 2448 TA Pro USB. As the mustek_usb2 backend
that supports it is beta (since 2008...), there is no config file in
/etc/sane.d for it. So I cloned the backends repo, changed the deviceid
to mine (0409 -> 040b), recompiled with ./configure
BACKENDS="muskted_usb2" and replaced
/usr/lib/x86_64-linux-gnu/sane/libsane-mustek_usb2.so.1.0.31 with the
recompiled binary.
When I plug the scanner, scanimage -L detects it as the BearPaw scanner.
I just had a black image at output and bad noises (that might break my
scanner, so I tried it only once). I guess I don't have the previous
error because it is the same chipset (not indicated by sane-find-scanner
nor scanimage -L), but all commands to the scanner must be bad as they
are different devices.
My programming skills are far away from programming an extension of such
a driver. Is there anyone out there that would be able to do this, or if
I should definitively give up on this ?
