 access USB scanners.  In Linux 2.6.4 the kernel scanner module was removed.
 Therefore with this and later kernels libusb must be used.
 
+Permissions:
+------------
 While SANE automatically uses libusb when the library and its header file were
 present during the build of sane-backends, setting permissions will require some
 attention. So if scanimage -L lists your scanner as root but not as normal user
 read on this text.
 
+Most distributions support setting permissions without much manual
+configuration. Usually you must just add the users that are allowed to access
+the scanner to group "scanner". To make that change active, the user must login

+README.debian.gz. If this doesn't work you you want to know more, read on.

 The device files used by libusb are located in /proc/bus/usb/
 (e.g. /proc/bus/usb/001/003) or in /dev/bus/usb/ (e.g. /dev/bus/usb/001/003), if
 you use udev.  The exact file name can be found out by running sane-find-scanner

+One solution to set permissions on-the-fly is Linux udev which comes with
+current distributions. SANE comes with a udev rules file in the tools/udev
+directory which may be used by distributions or can be copied to
+/etc/udev/rules.d manually. The file format is explained on top of the file
+itself. Either you need libusb 0.1.12 or newer or USB_DEVFS_PATH=/dev/bus/usb
+must be exported as a system-wide environment variable.
 
+Older distributions may use the Linux hot-plug tools (or hotplug-ng). Your

 If you build SANE from source you can use the hotplug script that comes with
 SANE. See the tools/hotplug/ directory in the source distribution. Please refer
 to the README in that directory for the details.

 Gentoo users: If your USB scanner is not detected at all check that USE=usb is
 set when emerging.
