That's about where I cheated and changed it to:
chown root:scanner $DEVICE && chmod 0660 $DEVICE
I'm not exactly sure the order parameters are passed to the RUN+
script from udev, so I can't say whether $3 and $4 are actually
correct.
On the other hand, if udev only provides a group, and $3 is that
group, then 'chown $3' is technically wrong and could very well be the
cause.

I am fumbling here, but /etc/hotplug.d/usb/libsane.hotplug is not too long
and says around line 27
chown $3 $DEVICE && chmod $4 $DEVICE
Can it be that this relates to the info taken from /etc/udev/rules.d
(see above), cos if so $3 and $4 are reversed? Or is that too obvious...

I had already looked there, and /etc/udev/rules.d contains the line:
# Epson Corp.|Perfection 1260
SYSFS{idVendor}=="04b8", SYSFS{idProduct}=="011d", MODE="660", GROUP="sca\
nner", RUN+="/etc/hotplug.d/usb/libsane.hotplug"
Which sounds perfect to me. Must be more to it than that, I guess.
Sounds perfect, but it's not. Did you check and see what damage
/etc/hotplug.d/usb/libsane.hotplug might be doing? It _could_ be
undoing the permissions.
This sounds exactly like the same issue as I reported a few days ago on this
list with gphoto2 and a USB camera. The USB device node was not updated
to have
the correct group ownership by the hotplug scripts. I didn't receive an answer
on that question though. Maybe this is more of a generic issue where
permissions on USB device are not set correctly, regardless of whether it's a
camera or scanner?

Sounds perfect, but it's not. Did you check and see what damage
/etc/hotplug.d/usb/libsane.hotplug might be doing? It _could_ be
undoing the permissions.
It's been a while since I messed with my scanner, but I think I
remember having something similar happen, I just edited the libsane
script and forced the permissions at the end. not very graceful, but
I was annoyed. :)

You will :) Until the script(s) are sorted out, you will...

I had a feeling that was necessary, but perhaps it was > overkill. But yes, it is inelegant. Hmm. It might be useful to post the output of 'sane-find-scanner', and 'sudo sane-find-scanner'(or however you want to run the command as root) What are the 'default' permissions and group (assigned by udev) on your scanner device? Perhaps you could try unplugging the scanner and confirming that the appropriate device file is being removed/created by udev. If udev is indeed handling the device, then the application of the rules file (/etc/udev/rules.d/025_libsane.rules on my box) is either borked (reinstall libsane and/or udev), or there are multiple rules matching your scanner (and the last one is screwing up the permissions set by libsane.rules). -- Brad -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".

I had already looked there, and /etc/udev/rules.d contains the line:
# Epson Corp.|Perfection 1260
SYSFS{idVendor}=="04b8", SYSFS{idProduct}=="011d", MODE="660", GROUP="sca\

Which sounds perfect to me. Must be more to it than that, I guess.

That worked. But I hope I don't have to do it manually every time I
reboot or hotplug the device.
