I have to admit to not really understanding the output of `lsusb -v`  
but I didn't see how to tie a device to a part number, however....

If they are the same device and you like it that way (e.g. I'm using  
Keyspans because they actually work, unlike others I've tried) you  
could put two different USB hubs in the chain, and figure out which  
device is connected to which hub, then do the right thing by parsing  
`lsusb -t`.

I know, men have been shot for more elegant solutions.
