I’m sorry I’m new to Ubuntu so I’ll try be as descriptive as possible.
At the moment my mouse is working when plugged into a specific USB port on the back of my PC. However when I move it to another port it doesn’t work. If I plug my keyboard into this same USB port then the keyboard will work and the mouse won’t. I have my system on a dual boot at the moment and I know for a fact that both the mouse and keyboard do work, it’s only when I reach the login screen that I have issues with my keyboard/mouse. I have tried other solutions given on this site and elsewhere but they don’t seem to work.
Like I said I’m new to Ubuntu and Linux as a whole so I’m sorry if this is an obvious question.

I have a Canon P-208II, which uses the
canon_dr backend .
However, I noticed from
lsusb that the product ID of mine (
0x1660) differs from that in
0x165f), so I duplicated those lines, modifying the ID to match.
Bus 001 Device 017: ID 1083:1660 Canon Electronics, Inc. CANON P-208II
Despite that, neither
scanimage -L detect the scanner, with verbose logging I can see it trying to access and getting permissions errors, or with root:
could not fetch string descriptor: Pipe error
in the same location.
I also tried
sane-find-scanner /dev/usb/001/017, which says
failed to open (Invalid argument) – I’m not sure what else to give as ‘devname’ ?
Is there somewhere else I need to change the product ID, or something to do to make the changes I have made take effect? Or is the pipe error a smoking gun?
