[sane-devel] Canon laser multi-functional support: MFNP protocol

[Rolf Bensch]

Hi,

I just committed several fixes for the MF6100 Series to Sane's git
repository.

Everything is working now: Flatbed, ADF and ADFDUP.

On a USB connection the scanner usual timeouts the 1st usb command after
a previous scan. I fixed this by resending the failed command. This
doesn't affect ethernet connections. Maybe somebody can find the reason
why the timeout occurs on USB.

My favourite gui for ADF and ADFDUP is gscan2pdf.

Cheers,
Rolf
