Issue with USB 3.0 controller

[NewbieG]

Hello List,

So far, fascinated with Qubes-os. I'm having an issue though: cannot use my USB 3.0 port. I've tried to follow instructions from https://www.qubes-os.org/doc/assigning-devices/ with no luck so far.

#lspci -k

Any hints that might help me find the problem?

Thanks in advance!

What do you mean you are unable to use it? Did you assign its controller to a usbvm? Are you able to use other usb ports? Checked your bios settings?

Unable to use it with qubes-os. Works like a charm if I boot off a live CD with -say- Ubuntu. And yes, I'm able to use another USB 2.0 port.
I've tried assigning it to a usbvm, but then I remove it (VM).
Thanks.

Can you try rephrasing that last sentence (or expounding)?

Also, have you already had a look at this page?
