AirSane is not showing scanner that scanimage -L shows #25

Hi! This is a recent problem that didn't appear weeks (or months) ago when I installed AirSane for the first time. The problem appeared on a RaspberryPi 3 B+ with Raspbian Buster.

I followed all instructions for installing AirSane, I have done it before with same scanner and same Raspberry Pi but on Raspbian Stretch and worked perfectly. Now it installed nicely but AirSane is not showing the scanner.

If I run sudo scanimage -L I get the right scanner: device epson2:libusb:001:004 is a Epson GT-9800 flatbed scanner

But on the AirSane server I get that there are no scanners:

Scanners

No scanners available

Any idea what can be causing this problem?

And by the way, thanks for such a wonderful tool...

Hi,

there might be a problem with device permissions. When you run scanimage as user saned, will it list the scanner? sudo su - saned scanimage -L

Thanks for your response

If I run sudo su - saned scanimage -L I get su: invalid option -- 'L'

But if I run sudo su - saned scanimage-L then I get:

su: warning: cannot change directory to /var/lib/saned: No such file or directory

Sorry, the command does not work for users without a shell, and there were quotes missing, too. The correct command is sudo -u saned scanimage -L.

When I run sudo -u saned scanimage -L I get that No scanners were identified. How can I change the device permissions to the saned user?

Thanks for your help!

Apparently, there is a bug in the udev rules coming with libsaned on Debian Buster. In the readme file, I added a note how to work around this under "Install".
