Hi Andreas,
I'm interested in more information about the Genius scanner. Can you please
enable the debug feature in the Makefile (enable the uncommented line #Debug=y),
recompile and reload the driver, and send the output of dmesg to this list.
I also need the output of
cat /proc/pt_drv/device0/info
So I might cna pin down the differences between the Genius device and the PT12.
Please send the stuff directly to this list
Thanks
Gerhard
