[sane-devel] pixma mg7500 testing

[Martin]

Hi Rolf

I've tested the latest version of the sane backend for Canon Pixma 
MG7550 with USB-connection. For me it works fine. xsane and the 
Gimp-plugin initialize all right and the picture is as it should be.

Many thanks for your work.

Best regards,
Martin
