[sane-devel] Problem with SnapScan 1212u

[ripero84]

Hello,

Apologies if this is the wrong list to ask for help with this issue.

I have an old Agfa SnapScan 1212u which was working fine when connected to an old computer 
A.  A debian dist-upgrade went wrong on A, and all my attempts to scan since then have failed.

So far I have tried to scan from two newer computers (B, C) that run debian stable, as 
well as computer A running a very recent debian live CD.  In each of the computers I have 
tried attaching the USB cable to multiple ports.  I have also tried two different USB cables.

I usually get an error of the form "Failed to open device `snapscan:libusb:001:008': Error 
during device I/O."  The exception is that, after I run (as user)

$ scanimage -L
device `snapscan:libusb:001:008' is a AGFA SNAPSCAN flatbed scanner

the error message changes to "no devices available" (but lsusb continues to list the device).

In each of the 3 systems, the SnapScan .bin driver I have always used has been copied to 
the /usr/share/sane/snapscan/ directory, and I have changed the firmware line of 
/etc/sane.d/snapscan.conf accordingly.

A sample output of lsusb -v -v can be found on https://paste.debian.net/1006235/ .  Some 
of the scanner lines (starting in line 979) show "(error)"s, and the device status is 
reported as bus powered, when the device is actually powered by being attached to the 
mains by a little provided transformer (and the device still makes the usual noise when it 
is powered on).

Am I missing something, or doing something wrong?  Is there any way I can make this 
scanner work again?

Thank you for your help.

Kind regards,

	JM
