>Description:
	Make the Epson CX3500, CX3600 and CX3650 MFPs work with sane (ports/graphics/sane-backends). I have tested it with my CX3650.

	There is still one problem: The uscanner module seems to conflict with the ulpt module. If the ulpt module is loaded first, the /dev/ulpt0 and /dev/unlpt0 device nodes are created, but not /dev/uscanner0; and vice versa.
>How-To-Repeat:
	A) Install the sane-backends port, load the uscanner kernel module, and turn on the printer. A ugen0 device appears, but no uscanner0, and sane-find-scanner doesn't find the scanner. With the patches applied, a uscanner0 device appears instead of ugen0, sane-find-scanner recognizes the scanner, and scanimage works.
	B) Load the ulpt module and then the uscanner module. Then turn the printer on. Even with the patches applied, there will be no /dev/uscanner0.
>Fix:
I am not sure about the USC_KEEP_OPEN flag, but the CX3500/3600/3650 series is supposed to be similar to the CX3200.
