I have the most recent version (scangearmp2_3.40-1_amd64.deb) of the software from canon. As the title says everything works fine for my installation with 16.04, but not for 18.04. sane-find-scanner returns
found USB scanner (vendor=0x0bda [Realtek], product=0x8153 [USB 10/100/1000 LAN]) at libusb:004:003
found USB scanner (vendor=0x04a9 [Canon], product=0x1792 [MB2700 series]) at libusb:003:003
However, scangearmp2 returns Cannot find available scanners. simple-scan does no better.
I can print to the MB2720 via usb without problems.
Could somebody advise on how to proceed?
This thread suggests that this may in fact be an 18.04 bug?
