Understand. I did not mean the log would help figure it out, but that it 
would explain that the card really is present. :)

My guess is that it is prematurely unloading the driver before it's 
fully registered, like you said. The question is why? Also I am not in 
front of the system right now so I can't unload the module to see if it 
generates the error again, but I will try it when I get home.
