[sane-devel] Testing on Canon MF6580PL

[Nicolas Martin]

The "process" here under is probably not an application, but runs in
background, it may be a printing daemon or service started after boot, which
locks access to the usb port.
I really know nothing about Mac OS X, to help you find it, maybe stop a
printing service would help.
