This will show you what is hanging on which bus. Ideally you want to try
different sockets until you find one that has nothing else on it.

I don't know the sound card you are using, or how old it is, or even how well
it's firmware supports USB2, but USB2 speeds on modern cards can easily manage
64/2 at 48k. Indeed, mine can (just) manage 16/2 at 48k.
Thanks Will, that makes sense.

I assume that the bus can only be changed by physically attaching the
devices to different ports. Is that right? The audio interface (Texas
Instruments, A Behringer mixer) already is plugged in its own USB port,
I might see if a different port changes something.
