[sane-devel] Support for Epson Stylus CX3650 multifunction device

[Robin Smidsrød]

It seems like this device could be easily supported. A customer of mine 
recently got it to work with XSane.
The printer part is well supported with Epson Stylus CX3200 driver 
(CUPS). See linuxprinting.org entry for that printer

Added the vendor/device id's to /etc/sane.d/epson.conf, and added this 
in /etc/hotplug/usb/libsane.usermap:

----- /etc/sane.d/epson.conf --------------
usb 0x04b8 0x080e
---------------------------------------------------

------ /etc/hotplug/usb/libsane.usermap ----------
libusbscanner             0x0003      0x04b8   0x080e    0x0000       
0x0000       0x00         0x00            0x00            
0x00            0x00               0x00               0x00000000
---------------------------------------------------------------

Things work as expected. Can't vouch for color quality or anything, but 
at least access and usage works.
