You have a USB3 root hub, but whether you have working USB3 ports,
it depends. Simplest is to look at mobo specs, the mobo
info can usually be extracted from the output of "dmidecode".

Then you need to check possible errata - back in early USB2 days,
mobos with some AMD chipsets had USB2 hardware that did not work.

Now in early USB3 days I have some mobos that need special linux
kernel command line switches to make USB2 work (or to make USB3 work,
I forget which).
