Hi, this scanner with USBVID=04a9,PID220D has a LM9833 which is supposedly supported by the plustek_usb backend, but Henning wrote in private email the CIS sensor would be a potential problem.
Though in mustek_usb CIS sensors are supported. What should I try? I already have usbsnoopy traces, would these allow to derive the sensor parameters? Regards, Gunther
