I had a Medion flatbed scanner MD/LT 9385 working on my Manjaro Linux (currently kernel 3.9.7-1, x86_64), by just uncommenting the necessary lines in /etc/sane.d/gt68xx.conf and putting the firmware gt680xfw.usb in /usr/share/sane/gt68xx/ Last week the scanner failed, so I bought a brand new Plustek Opticslim 2600, also gt68xx based (GT6816 chip). I hoped that the same procedure would work again. I added the following lines to /etc/sane.d/gt68xx.conf: # Autodetect Plustek OpticSlim 2600 usb 0x07b3 0x0467 model "OpticSlim 2600" override "plustek-opticslim-2400" firmware "/usr/share/sane/gt68xx/cis3R5B1.fw" afe 0x20 0x02 0x22 0x03 0x1f 0x04
and put the required firmware in place. Things don't work however: ?lsusb Bus 001 Device 002: ID 072f:9000 Advanced Card Systems, Ltd ACR38 AC1038-based Smart Card Reader Bus 002 Device 002: ID 07b3:0467 Plustek, Inc.
