I believe the best solution is to add a udev rule that causes your MCE 
remote's USB receiver to be created as device with a known name. Then, 
you can set the parameters for your lircd daemon to point to this 
device. Essentially, this is what I do in MiniMyth.

You can find an example of what you might do here:
<http://www.mythtv.org/wiki/Volume_Knob_on_Antec_Fusion#Edit_udev_rules>. 
It shows how to create a symlink to the device based on the USB vendor 
id. This should be sufficient for what you need. However, you can 
qualify it further using the USB device id and/or the USB serial number.
