Scanner Permissions

Ref: Linux Format May 2009, page 105

Issue: Scanner is not recognized and cannot be started from Gimp.

Resolution:

1. Creat a group called “scanner”, and a group called “usb”

2. Create a file called “10-scanner.rules”. This file is located in /etc/udev/rules.d/


This file contains the following:

#Scanner rules for Epson Perfection Photo 3170

ATTR{idVendor}=”04b8″,

ATTR{idProduct}=”0116″,

GROUP:=”scanner”,

MODE=”0660″

LABEL=”10-scanner.rules_end”

Method:

1.  Choose “System Settings”, then go to “User Management”, click on “Groups”, and add a group for “usb” and “scanner”, if these are not already on the system.

2. Start a BASH (Konsole) and go “sudo GEDIT”. Create file called “10-scanner.rules” enter the information given above.

If it is a different scanner to the EPSON Perfection 3170, then you will need to change the entries to match.

To find the appropriate entry for your scanner type

lsusb

This will produce output such as:

Bus 001 Device 004: ID 04b8:0116 Seiko Epson Corp. Perfection 3170 (GT-9400)

In this example, under “ID” we have 04b8 for “Vendor” and 0116 for “Product”

ATTR{idVendor}=”04b8″,
ATTR{idProduct}=”0116″,

After you have saved this information in the file called “10-scanner.rules”, ( located in /etc/udev/rules.d/) your scanner will now work from GIMP. (GNU Image Manipulation Program)
