the udev rule should replace the enabler make sure you have the current version installed of the scanner software the ID of scanners can change (non-HP ones in my exp) i know at some point i made the scanner detected and change the id to the new one, before this was done you had to recheck for scanners to get it working
the udev rule is made by the main installer, not the updater
edit
check your /etc/udev/rules.d/40-scanner.rules
file
for example on a ubuntu install
cat /etc/udev/rules.d/40-scanner.rules
SUBSYSTEMS=="usb", ATTRS{idVendor}=="1606", ATTRS{idProduct}=="0060", ENV{libsane_matched}="yes", GROUP="lp"
that grants non root access to all users of the lp group (and unless my system i acting odd the lpadmin group also)
the 1606 and 0060 can be found in the output of lsusb
The clone of this git repository is current. The scanner is a Canon, it is very new and does not have support in the current Ubuntu repositories. Support is via PPA at https://launchpad.net/~rolfbensch/+archive/ubuntu/sane-git
After unplugging and plugging in the scanner, running the udev rule script gives the following output:
You have rules, but something is different /etc/udev/rules.d/40-scanner.rules has:
1 Bus 004 Device 004: ID 04a9:190f Canon, Inc.
#----END-OF-FILE----
These are the new rules:
1 Bus 004 Device 007: ID 04a9:190f Canon, Inc.
#----END-OF-FILE----
No action taken, you can edit /etc/udev/rules.d/40-scanner.rules as you see fit
However, running the enabler allows it to work again.
the rule was not created cause the script avoids altering you existing configs however it looks like when i made that script i forgot to have it tell you the rule it would have added
if you had said rule it would/should work, but you lack said rule
edit: odd it looks like the script is dumping the lsusb output to it, guess the script is broken
http://pastebin.com/NTsSKR4z can you post the output of this one so i can find the issue?

The one with Device 004 would have been created when I first ran the script last weekend. Unplugging the scanner and plugging it in again gives it a new Device ID of 007
http://pastebin.com/n4jtv3Gk
try that script see if it makes a rule that looks right and works
if you don't want to make the file manually delete /etc/udev/rules.d/40-scanner.rules
sudo rm /etc/udev/rules.d/40-scanner.rules
your current file is useless and was made by my broken code, no idea when it broke but it did
chown: cannot access ‘/dev/bus/usb/04a9’: No such file or directory chown: cannot access ‘190f’: No such file or directory /etc/udev/rules.d/40-scanner.rules is good to go
looking in the usb devices: bananapi@lemaker:~/PHP-Scanner-Server$ ls /dev/bus/usb/00 001/ 002/ 003/ 004/ 005/
Each of these usb directories has a single file 001 listed as a character device:
bananapi@lemaker:~/PHP-Scanner-Server$ ls /dev/bus/usb/001/ -la total 0 drwxr-xr-x 2 root root 60 Jan 1 1970 . drwxr-xr-x 7 root root 140 Jan 1 1970 .. crw-rw-r-- 1 root root 189, 0 Jan 1 2010 001
try this one http://pastebin.com/fxytaDJG (nrv, not ready)
*the only scanner i have to test this is not plugged in and need BIOS settings changed
i think this is what you should have in the rule file
~$ cat /etc/udev/rules.d/40-scanner.rules
SUBSYSTEMS=="usb", ATTRS{idVendor}=="04a9", ATTRS{idProduct}=="190f", ENV{libsane_matched}="yes", GROUP="lp"
This one should work http://pastebin.com/fttFAj7x if it gives no errors and you can unplug and plug it back a few times without issues i will update the file to this one
The script at http://pastebin.com/fttFAj7x works. Configure, Search For Scanners button finds it.
I have removed the access enabler from running at boot. After rebooting, unplugging and plugging a few times, I can still scan.
Thanks for letting me know that script broke
If a usb scanner is unplugged and plugged in again, the enabler needs to be run again. Can it be added to the udev rule ?
I presume then it would not be needed in /etc/rc.local
