It seems the CX-3700 is currently supported by both the epkowa backend 
and the epson backend. It's definitely not supported by the snapscan 
backend, so anything mentioned on snapscan.sourceforge.net doesn't 
apply.

I'm not an expert on the epson backend, but it should be able to 
recognize your scanner if you just put the IDs into epson.conf, e.g. 

usb 0x04b8 0x0818

After that your sanner should be recognized by scanimage -L.

The epkowa backend is not part of the SANE distribution, you have to 
install it separately. You can get it from 
http://www.avasys.jp/english/linux_e/dl_scan.html . It also provides 
it's own documentation.
