Hmm...seems like there should be an app to do this but there isn't 
(don't think you can directly figure out driver or /dev/ file using 
lspci or lsusb, so the simple answer seems to be that you can't).

If you look at lspci -vvv (especially with -m to simplify it), it gives 
mainly low level setup details like IRQ and addresses, it does very 
little with respect to drivers or devices (the bus doesn't care about 
that part), but it does give you one or two clues. Maybe someone will 
one day write a program that goes through the device discovery process 
and prints out the details as it goes (without actually doing anything).
