Using sane-find-scanner I find that my scanner is at libusb:001:002. Now
I'm trying to chmod libusb:001:002 so I can access it with xsane, but
there's no /dev/bus/usb/001/002. I did locate
#ls -l /proc/bus/usb/001/002
-rw-r--r-- 1 root root 57 Oct 29 16:16 /proc/bus/usb/001/002
but I'd better not chmod this. What should I do?
