Public bug reported:
I noticed that every device I plugged in to the USB-C port on my
computer (which is USB 3.1 or, should I say, 3.2 Gen. 2 - WTF those
names), it only runs at 2.0 speeds (480Mbps). After doing some
troubleshooting, here's what I discovered:
If I shut down my machine, plug my USB 3 device in to the USB-C port,
power it on and let the OS boots... it works at 3.x speeds just fine
until I unplug it; The moment I plug it back in, the exact same USB 3
device at the exact same USB-C port at the exact same orientation, it
starts to run at 2.0 speeds.

This happens only with the USB-C port, the USB-A 3.x works perfectly all
the time.
Some forums suggested adding iommu=soft parameter on my boot entry, no
changes; others suggested turning off Legacy USB support at UEFI/BIOS
Menu but that option doesn't exist on my machine.
My machine is a Clevo NJ70MU laptop, OS is Ubuntu MATE 22.04.1 but I
made the same test with a LiveUSB running Ubuntu (vanilla) 22.04.1,
Debian 11.0.5 and Arch (2022.09.03) ISOs, the results are exactly the
same.

This happens only with the USB-C port, the USB-A 3.x works perfectly
all the time.
Some forums suggested adding iommu=soft parameter on my boot entry, no
changes; others suggested turning off Legacy USB support at UEFI/BIOS
Menu but that option doesn't exist on my machine.
My machine is a Clevo NJ70MU laptop, OS is Ubuntu MATE 22.04.1 but I
made the same test with a LiveUSB running Ubuntu (vanilla) 22.04.1,
Debian 11.0.5 and Arch (2022.09.03) ISOs, the results are exactly the
same.
