Hi,
I just tested and have a Myiro-1 and i1D3 both working at the same time connected to a USB 3 powered hub which itself is connected to a USB3 cable extension.
The only limitation I found is you need to plug the whole apparatus directly into a USB port on your computer.
Originally I tried with the USB 3 extension connected to my laptop dock. However that threw a windows error saying your hub won't work as its 5 hubs away.
I guess the active USB 3 cable's electronics are considered USB hubs. Interesting.
Anyhow, here is the links to these items:
