[sane-devel] Canon PIXMA MG6400 Series

[Rolf Bensch]

Hi Chris,

Attached patch should fix your issue. The patch fixes this file:
backend/pixma_mp150.c.

Please also test the USB connection without WiFi connected.

After your positive feedback I'll update the sources in SANE's git
repository.

Cheers,
Rolf
