Trouble with USB3 chipset uPD720201

That kernel is way too old. Initial usb 3 support was added to 2.6, but the real support for xhci was added in 4.4-4.6. It's part of the linux-firmware load as well as the kernel proper.

Keep in mind that you should attempt to upgrade the firmware first, http://www.station-drivers.com/index.php?option=com_remository&Itemid=353&func=select&id=438&lang=en(via bootable windows emulation), then the kernel(preferably 4.6.3 at the time of this writing), http://kernel.ubuntu.com/~kernel-ppa/mainline/. If you've never upgraded a kernel before, it's very simple. 3 files(amd64 generic header & image & all.deb), one command(dpkg -i headers.deb image.deb), reboot, and you're done.
