hello everyone, today I try install skanlite on Fedora 34 KDE, but after run skanlite, there is no scanner device, and I also try to check via scanimage, still there is no scanner detected…
this problem appears only in Fedora 34… before this, I already install Fedora 33 and scanner running and get detected without any problem…
my scanner is the old one, Canon LiDE 110…
this is command when install skanlite & sane-backends :
sudo dnf install skanlite sane-backends
this is the image when I try to open Skanlite :
this is output from scanimage -L (with and without sudo):
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).
this is output from sane-find-scanner :
# sane-find-scanner will now attempt to detect your scanner. If the
# result is different from what you expected, first make sure your
# scanner is powered up and properly connected to your computer.
# No SCSI scanners found. If you expected something different, make sure that
# you have loaded a kernel SCSI driver for your SCSI adapter.

# Your USB scanner was (probably) detected. It may or may not be supported by

# Most Scanners connected to the parallel port or other proprietary ports
