Check :

Check : firmware /usr/share/iscan/esfw52.bin

and /usr/share/iscan/esfw52.bin does exist.

I got already several from these packages, and a few months ago I

As a last resort, I tried it as an ordinary user instead of

So, using the scanner as root blocks on listing devices, but as an
ordinary user (member of group scanner) this works.

Alright,
