update: Just found out that there IS a new driver package supplied by the vendor:
http://support.epson.net/linux/en/iscan.php?model=perfection-v330&version=2.30.4 However, it has different issues. Purged my previous 1.0.0 and installed the 2.30.4. Installation appears to run smoothly - no obvious errors. But instead of access problems, the scanner is not even visible now. Tried both manual package installation and running their install.sh - same result there now is a /lib/udev/rules.d/60-iscan.rules with size 39047 so my hack from the first post will no longer work. Instead, I found this hint: https://www.ryananddebi.com/2018/05/26/linux-fixing-the-epson-v33-perfection-scanner-issue-in-kubuntu-18-04/ I didn't softlink any libraries, since there is already a usr/lib/x86_64-linux-gnu/sane/libsane-epkowa.so.1 -> ../../sane/libsane-epkowa.so.1.0.15 However, I added this rule: ...$cat /etc/udev/rules.d/79-udev-epson.rules # wr 2019-12-20 for epson V33 scanner #https://www.ryananddebi.com/2018/05/26/linux-fixing-the-epson-v33-perfection-scanner-issue-in-kubuntu-18-04/ # chmod device EPSON group ATTRS{manufacturer}=="EPSON", DRIVERS=="usb", SUBSYSTEMS=="usb", ATTRS{idVendor}=="04b8", ATTRS{idProduct}=="*", MODE="0777" and - voila - it works again. I don't see any obvious difference between 2.30.4 and 1.0.0 still the pre-beta style user interface :-( Anyway, I think it really would be nice to have this iscan packages coherently maintained within the debian framework. Maybe it could go to non-free? There is a README.rst in the driver package mentioning some licensing issues. Who's job is this? Who elses than the manufacturers? For my part, the next time I'll buy a scanner, I will start with the list of native sane support ;-) regards -- Wolfgang Rosner
