He was, but I see it has evolved from there. In the link I gave you (and 
follow it to http://ubuntuforums.org/showthread.php?t=756508) a person 
named "grytpype" modified the script to accept node number and it also 
fixes an issue with "scrambled channel digits" that is in the current 
contrib. Grytpype's version works well for me.

The one on node 1 looks close. I've seen model 10cc before but with a 
different vendor_id. You will need to change the corresponding vendor_id 
and model_id's in the code to get this to match.

What does "plugreport" show you?

Personally, I don't bother with the device checks any more because I am 
using the GUID and converting it to a node number.
