I take inspiration from another thread on this mailing list to complete the information.

My configuration seemed to be vanilla to me, but then I realize that there is nothing vanilla in trying to help remote troubleshooting, so to complete the information: > [...] and expected canon configuration file (pixma.conf, I think)? actually there is no pixma.conf file, just four (!) files starting with canon. quite confusing, but not critically so as I was able to get around. > $ dpkg-query --show libsane libsane:amd64 1.0.23-0ubuntu3 the stock 'buntu one.

Could it be that I am experiencing this bug: <https://bugs.launchpad.net/ubuntu/+source/sane-backends/+bug/313504>? I am not convinced, because (1) scanimage does not even get to the errors during device I/O (2) even blacklisting usbpl and usb_storage (for testing purposes only, my father-in-law will kill me if his external USB backup drive stops working) did not change anything. And back to the specific situation with the MF4570dw, I am more interested to get it to work over ethernet/wifi than over USB. Any ideas?
