$ sane-find-scanner
found USB scanner (vendor=0x04a9 [Canon], product=0x190f [CanoScan])
at libusb:003:002 could not open USB device 0x1d6b/0x0002 at 003:001:
Access denied (insufficient permissions)
This looks like a permission problem: the user who executed
sane-find-scanner is not allowed to access the scanner device.
A "quick and dirty" test to verify this is to run sane-find-scanner as
root. For example:
sudo sane-find-scanner
The udev mechanism controls permissions assigned to devices - use "man
udev" to learn more. For my Epson scanner, I use the configuration file
that follows (change vendor and product codes to match your scanner; lines
that begin with # are comments):
# File: /etc/udev/rules.d/10.local.rules
# Local (RWR) rules for udev.
# Epson scanner idVendor=04b8, idProduct=012c
SUBSYSTEMS=="usb", ACTION="" ATTRS{idVendor}=="04b8", ATTRS{idProduct}=="012c", GROUP="users", MODE="0666"
Richard,
Excuse me... actually we the solution? I am only a user... ;)
