Cannot scan with Canon MP620 since upgrading to OS X Yosemite.
Since I upgraded my iMac to OS X Yosemite my scanner, a Canon MP620 series does not work anymore. the Image Capture window displays: "no scanner or camera connected". The Canon scanner/printer is definitely connected to there iMac, I can actually still print.
iMac (21.5-inch, Late 2012), OS X Yosemite (10.10), Canon MP620 series
