[sane-devel] Canon PIXMA MX925 - scan process now broken (does not end)

[Stephen Weston]

Hi,

Had a go with the Ubuntu test ppa after a fresh install of Ubuntu 17.04 in
VirtualBox. The terminal output is as below. As you can see the scanner was
successfully detected and the initial scan worked, but the scanner was left
in a busy 'scanning...' state and a second attempt at scanning did not work.
