As I've found now the origin of '/etc/udev/rules.d/79-udev-epson.rules'
- it was installed by the epson-printer-utility for my Epson XP 540 - I
tried what happens when I switch to a more 'common' udev rule.
I tried (similiar to the rule for brother scanners provided by Hans):
ATTRS{idVendor}=="04b8", ATTRS{idProduct}=="*", MODE="0664",
GROUP="scanner", ENV{libsane_matched}="yes"
Result: No firmware up-load, no scanner found. As soon as a I switch
back to the rule installed by epson the scanner starts (after switching
off-on) to up-load the firmware and is accessible by scanning programs
(as non-root).
@luca
can you please try the following udev rule (scanner is locally attached
via usb, please keep the current one stored at an other place, no
garantuee, so you may want to revert) :
/etc/udev/rules.d/79-udev-brother.rules
# chmod device BROTHER group
ATTRS{manufacturer}=="BROTHER", DRIVERS=="usb", SUBSYSTEMS=="usb",
ATTRS{idVendor}=="04f9", ATTRS{idProduct}=="*", MODE="0777"

Title:
Many 3rd party scanner drivers are broken by a sane change
Status in sane-backends package in Ubuntu:
Confirmed
Bug description:
Many scanners can no more be used since sane has changed something:
The 3rd-party plug-in the vendor provides as .deb package will still
install. But the scanner is no more recognized.
Scanners that are affected are(besides others):
- Epson Perfection V10
- Epson Perfection V1000
- Epson WorkForce GT-1500
- Brother MFC-8510DN
- Epson Perfection V33
It is to note that the probability that the scanner manufacturers fix
things others broke is below 100%.
