Every Linux OS I've run on directly on the hardware has had this issue. I'm currently running 14.04. The above/recent details are from running a Xenial off a USB flash. I've previously tried 15.10 with the same results.
USB pass-through gives high-speed direct access of the USB hardware to the guest operating system. Fedora 22 and Kubuntu have the same problem.

I use win7 in a VM for HD video chat.
