[sane-devel] Artec 1236USB (Unknown chip!)

[Theodore Kilgore]

Gerhard (and anyone else interested in the matter),

At this point (apologies for slowness, but it isn't my scanner) my friend
has run check-usb-scanner on his Artec 1236USB and captured the output to
a log file. Here is the result which unfortunately seems to me rather
negative.

Of course, it does actually seem to me that "Device Class 0" and
"Interface Class 0"  could be obvious lies intended to deceive the
ignorant, so if check-usb-scanner is depending on the device doing an
accurate self-report about its device class, subclass, and protocol, there
may be a problem there. Not all devices report themselves truthfully. For
an example, go to the Linux Working USB Devices list (at www.qbik.cz?) and
do a search for Trumpion.  You will find there a pocket MP3 player which
lies and says its protocol is Control/Bulk (01) instead of Bulk (50).

Anyway, here is the output.
