airsaned report no scanners available, though scanimage -L reports one #97
Description
I am trying to make AirSane build (https://aur.archlinux.org/packages/airsane-git) in archlinux to work.
I am starting airsaned via airsaned.service with:
DynamicUser=true
Group=scanner
SupplementaryGroups=lp
SupplementaryGroups=saned
It runs, but www frontend reports "AirSane Server on / No scanners available" :/
Switching to same user/groups I am able to detect scanner though:
[root@contr ~]# runuser -u airsaned -g scanner -G lp -G saned -- bash
[airsaned@contr root]$ scanimage -L
device `hpaio:/usb/Deskjet_F4200_series?serial=CN94O5828R05BR' is a Hewlett-Packard Deskjet_F4200_series all-in-one

Does it mean that scanner is not detectable to airsaned?
Due to message bus security policy can't be made available?
Or any other issue?
TIA for any hints.
