Hi guys,
I've had this annoying problem on my Broadwell X1C3 and I also have the same problem now on my new T460s Skylake.
Basically if I'm unlucky when I have both my USB microphone plugged in along with my USB uvcvideo [1], it can trigger this "Not enough bandwidth for new device state. " instability. It basically makes my USB microphone stutter or cause the incoming video to cut out.

Any ideas how I can solve this? I'm not entirely sure if it's a hardware issue or software issue.

Many thanks,

I can't tell if you are using USB 3.0 or not. If not, then likely you don't have enough band width. I have the same issue with a keyboard and mouse. My USB 3.0 hub+switch should be able to handle the load.
