I am trying to get a 3M AT9000 Document Reader (http://multimedia.3m.com/mws/media/611505O/sell-sheet-at9000.pdf) working via a RaspberryPi B+.
The device is detected properly and i can install the drivers. If i run the 3M troubleshooting tool which is included it detects the device OK. But when i do a Camera test i get an error.
Unfortunately i cannot find any relevant logging on client nor server side. So i do not have much to go on. Any suggestions what to check?
