(Fixed quoting, sort of.)

Yes, that's right. I'm not sure I can give you the exact details because I don't 
have your device but this page probably is what you need to look at:

http://www.mythtv.org/wiki/Device_Filenames_and_udev

What you will have to do is find out how your device is identified and write a 
rule to match it. The action you'll need won't be a SYMLINK one like a lot of 
the examples but a PROGRAM one which will run a script when your device gets 
detected.

udev has a testing option so that you can see what it will attempt to do. You 
can use this to get your rule working.
