[sane-devel] Problem with Button of HP ScanJet 6200C Scanner and scanbd

Sat Nov 17 08:59:24 UTC 2012

Hello Wilhelm,

Thank you for your help and your effort!

In the end it seem to be a hardware problem. The button on the front 
does not work any more - I disassembled the device and measured it out 
on the board.

However, I will by another adf scanner and know now how to setup scanbd.
Thanks again for the journey into scanbd configuration.

Regards,
Thomas
