Came across this thread which lead me to the answer. I could now get the needed information without shutting down the box, opening it up and hopefully finding the model number so I could google up the answers, etc. etc.
No GUI app need apply, I wanted a command line solution. Here are some options I found:
lspci -vv or sudo lspci -vv
But the really cool one is:
sudo lshw
That shows you just about everything you could want regarding your hardware. I found out what model mainboard I am running and the USB info I was looking for...
