I may take a look. The thing is that backend configuration and device
detection are two separate things. The epson2 backend doesn't read its
configuration file unless you do device detection. That smells.

There should be no need to do that. You either open the device that was
passed or the first supported device you find if the default was
requested. There is no point in trying to find all the the available,
supported devices in sane_open(). It would seriously suck if a call to
sane_open() for a *specific* device would end up doing, for example, a
broadcast for networked devices on a reasonably sized subnet with a ten
seconds timeout.
