Comment 2 for bug 1323784

I think this has a lot to do with the ever increasing number of USB devices
connected to a single dispatcher.

As I'm getting tired of the tc2-benchmark being a SPOF (terrible, terrible
idea there) I suggest we get a small form factor PC, something like the NUC
Alan had at connect, sit it on the shelf next to the tc2 and let it have
it's own dispatcher. No USB hubs, just a straight USB connection from the
device to the dispatcher..
