This begs the question of which versions of USB are involved in this 
setup of yours? For example, USB 3 is backward compatible with USB 2 but 
I not sure if it is with USB 1.1. And I don't think USB 1 will work with 
USB 3.

Also, how many devices are using the same USB port? If there are, say, 2 
devices then one of them will miss out if the other one is using the USB 
port.
