Howdy,

	I'm seeking help with getting an epson USB u636 scanner working with sane (xsane & scanimage). I've come down quite a long path to arrive at "it's just so close but not yet working". I hope to find the needed help to get the job done here.

	My current problem is that scanimage does not find my scanner. But note that sane-find-scanner does find it.

	sane-find-scanner reports:

	found USB scanner (vendor=0x04b8 [EPSON], product=0x0101 [Perfection636]) at libusb:-08:005

	I have compiled sane with libusb. I had to trick up both the libusb and the sane compile to get through. During the libusb compile, it failed to link and I had to manually run ranlib on libusb.a before the make would continue. During the sane compile, the compile failed during the cannon backend. I edited the make file to remove all the backend objects excpet for the epson object which I think is the only one I need (at least for the time being) (and I also had to do the famous apple -no-cpp-precomp in the CFLAGS.)

	But ok, they have compiled. And they installed just fine (seems like to me anyway).

	At this point sane-find-scanner is working and reporting my usb scanner. But scanimage -L cannot find it. 

	So I try to edit my /usr/local/etc/sane.d/epson.conf file to say
	usb libusb:-08:005

	Still scanimage -L cannot find it.

	So I tried to do a `mknod /dev/usbscanner0 c 180 48` with an appropriate `chmod`.

	Still scanimage -L cannot find it.

	xsane also cannot find the scanner through all of this either.



	What shall I try next? I'm willing to do some debugging work, but I don't have much of a good idea of what to try. How could I isolate if this is an epson-backend issue or a usb issue? Where would I go from there?

Thanks in advance
