I have a Epson L382 printer/scanner machine and i use the software available from Epson. The scanner software do not find the scanner - after the upgrade. sane-find-scanner write this: found USB scanner (vendor=0x04b8 [EPSON], product=0x1120 [L382 Series]) at libusb:002:004 could not open USB device 0x1d6b/0x0002 at 002:001: Access denied (insufficient permissions) scanimage -L write this: No scanners were identified. If you were expecting something different, check that the scanner is plugged in, turned on and detected by the sane-find-scanner tool (if appropriate). Please read the documentation which came with this software (README, FAQ, manpages). Any solution?

problems with permissions can normally be gotten around by using sudo .
Try this:
sudo sane-find-scanner
Be sure your scanner is on and plugged in.
The group of USB printer device is now lp
.
It is necessary for the user to be in group lp
.
You can use de command:
sudo adduser <username> lp
If you are in X session you need to logout and login again.
Confirm you have the lp
group with the command id
.
I'm on HP hardware and using HPLIP, but I had the same issue. The USB device is set up as owned by root:lp
, so you need to add saned
to the lp
group:
sudo usermod -a -G lp saned
