USB devices are allowed to reserve bandwidth... and that affects every

a USB hub" -- but that's not true. Your PC has one or two USB hubs
that it uses internally. In my case, I had a USB audio device on the
same hub as a USB Webcam. Even when I wasn't using the Webcam, it was
reserving bandwidth. Thing would be running fine, then all the sudden
audio comes crashing down with an xrun.

For me the PC had two internal hubs. I used a different USB port
(attached to the non-webcam-hub) and the problem was solved.

I'm not saying this is your problem... but use something like 'sudo
lsusb -t' and inspect which devices are connected to which hubs.
Unplug as much as you can. Try different ports.
