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.

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

Thanks a million.
