This is an Epson Perfection 1260. Don't ask what the 'Perfection' stands
for. Anyway, this is in fact a Plustek, so I have to add the following
to /usr/local/etc/sane.d/plustek.conf:
-[usb]
+[usb] 0x04B8 0x011D
+device /dev/uscanner0

I need vendor and product id to get this working. Without getting
this info, eg scanimage -L will complain that it couldn't find a scanner, etc.

only with /dev/usb* set to root:usb, I will get

%scanimage -L
device `plustek:/dev/uscanner0' is a Epson Perfection 1260/Photo USB flatbed scanner
