Why is a scanner on Linux such a pain?

Question

linux

I have been suffering for a long time, periodically I quit and go to get a laptop with Windows, but now I decided to fight a little more.
Installing Plustek MobileOffice S400 on Linux Mint.
Everything is as it should be, according to the instructions, of which the network is full.
# aptitude install sane xsane
Everything is fine, the programs are up and running. But nobody wants to see the scanner.
More precisely, they see him, even almost correctly define him.
# sane-find-scanner

At the same time, it works more correctly with root rights :)
# sudo sane-find-scanner

found USB scanner (vendor=0x0b05 [Realtek], product=0x17ab [802.11n WLAN Adapter]) at libusb:001:005
could not fetch string descriptor: Pipe error
found USB scanner (vendor=0x07b3, product=0x0465 [600dpi USB Scanner], chip=GT-6816) at libusb:001:003

Here it is, the scanner of my dreams - found USB scanner (vendor=0x07b3, product=0x0465 [600dpi USB Scanner], chip=GT-6816) at libusb:001:003
And everything would be fine, but our cart didn't go further.

# scanimage
scanimage: no SANE devices found
# scanimage -l
scanimage: no SANE devices found
# sudo scanimage
scanimage: no SANE devices found
# sudo scanimage -l
scanimage: no SANE devices found

Maybe someone faced already and won?

Answer 1

Hello Sergey!
Your scanner is not in the list of supported www.sane-project.org/lists/sane-mfgs-cvs.html#Z-PLUSTEK
I, at one time, when I introduced Linux in schools, simply exchanged scanners with the education department :) They didn’t care , and I got a scanner that works 100% on Linux.
If the scanner is personal, then it’s easier to buy any supported scanner for 500r on Avito (most HP work fine).

Answer 2

maybe there is a separate group of scanner users in the system, to which you want to add a user?

Answer 3

Use your USB scanner. where is the pain?
