Note: touchpad,  not a driver, so synaptics module is loaded for eGalax,
and of course it can't find touchpad

Note: Synaptics

So xorg unloads the synaptics module and gives up.

I stil can't see 2 devices in this log. If you mean this:

(--) eGalax Inc. USB TouchController: no supported touchpad found
(EE) eGalax Inc. USB TouchController Unable to query/initialize...

it is the message for same device, with different markers (--) probed, (EE) error

Yes and I apologise once again for rushing in without verifying which
version you are dealing with.
Why xorg or hal is pushing synaptics driver for the touchscreen is a
mystery and I can't check it myself, as I have no touchscreen at hand.
As I mentioned in my other post, maybe you can try to ditch "touch"
string from "info.product" key in fdi.
