Changing udev attribute

[wtfacoconut]

Here's the jist:

I have two touch screen monitors tha tI'm configuring for a dual-head display.

That is working.

For the touch screens it's a bit more complicated, each touch screen requires that I apply a specific config file for each individual TS (touch screen). Each config file is unique to it display. for that I'm using xinput to apply those configuration.

My problem here is that the TSs are the same model and show up under udev and xinput under the same the same name minus the different hardware IDs whish is the only way that I can currently distiguish them.

So far I've experimented with tweaking the udev rules for a particular TS with no luck (more than likely because I might be doing it wrong).

I ned to be able to tell the two appart when I apply the configurations in xinput so I can write a script that will do this automatically for me.

I know that I'm not giving that much information so please feel free to ask me for more if needed.

By "hardware IDs", are you referring to "serial" number? Not really an expert but I just happen to have a UDEV article from Linux Magazine at hand. Have you tried to add this into action rule?

ATTRS{serial}=="__serial-number-here__"

Hope this help.
