[sane-devel] Net Client Not Contacting Server

Well, bugger.  So much for my attempts to compile the backend lib.

I'll just get an extra-long USB cable to connect it to an x86_64 virtual

The reason I bought this scanner is it is one of the very few with the
hinge on the -long- side, not the -short- side.  Why do almost all
scanners require you to flop open a great long lid in order to change
papers?  Doesn't anyone have any sense?

Well I'll just be happy that networking is working now. It's hopeless to
ask for an arm64 driver from Epson. 

Thanks Olaf.
