Hi,
I recently had a bad freeze while playing a game (I think I ran out of vram) and the whole day afterwards while troubleshooting, the PC was very sluggish and I couldn’t even shutdown properly (had to manually hold down the power button every time).
I eventually fixed that issue by plugging in a live USB with Linux Mint and after rebooting, everything worked again, even though I changed nothing 
. However I noticed that my boot now takes over a minute, while it’d previously only been a few seconds.
I think I narrowed the Issue down to a USB port, but I can’t seem to find the physical port and I’m slowly loosing my mind. I plugged my keyboard into every port on my PC and checked dmesg, but I couldn’t find the port in question.
Here is the dmesg output of the error (as you can see, this fail at enumerating the USB device takes over a minute alone):
[ 4.047032] [ T679] usb 1-9: new high-speed USB device number 6 using xhci_hcd

I also changed the BIOS settings (legacy support, xhci hand-off, etc.), but that also changed nothing.
The weirdest thing is, whatever port I plug my keyboard into, it thinks it doesn’t have enough power and it doesn’t seem to matter if it’s labeled as 3.2, 2.1, 2.0 or whatever.

When I check with usbview, none of them look like a 3.2 usb port. And the real usb 3.2 hub is apparently somewhere on bus 2, but none of my physical ports seem to lead there.
The only port I can’t check is a USB-C port, because I don’t have the right cable for that, but I doubt that it is the one. In fact, I think that one would show up as port 1-1
I’m at my wits end, and I still don’t even know if it’s a hardware or software problem, please help.
