A couple of months ago, it happened that my epson 3590 worked. Once in a

Don't know about the driver. for the rights, see 
http://www.sane-project.org/README.linux. The forth paragraph says :

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
which would print "libusb:001:003" in this case.  While setting permissions with
e.g. "chmod a+rw /proc/bus/usb/001/003" works, this change is not permanent...
