[sane-devel] Error: Canon Pixma MG7550 hangs

[Martin]

Hi,

Today I built Sane 1.0.25 from the development repository.

But a software that tries to use the pixma backend hangs.
I tried scanimage --format tiff -x 10 -y10 > /dev/null, xsane and Gimp.

The scanner works if the first command after power-up is
"scanimage -T". After that the mentioned programs work fine.

Could anyone please look into this problem?

Martin
