Thanks again for taking the time,

I reduced the "info.product" key to just "eGalax" which didn't result in any 
changes.  I was wondering if there is any way to monitor what hal is matching/parsing?
I would love to verify that hal is reading the .fdi file (which I have in only 1 place).
BTW: looking at syslog, messages, etc -- doesn't report anything about this problem.

Thanks again,

Nasa

Oh, if there are any other troubleshooting methods I am missing -- I am open to any suggestions!
