Down clock USB 3.1 to 5 Gbit/s - eviltoast

Hey there fellow neck-beards and grey-beards!

I have a motherboard with USB3.1 and I need to down clock it so its always 5 Gbit/s and never faster.

Is there any way to do this, my DuckDuckGo Fu is not finding the right combination of words.

I use Arch BTW…

Just kidding im still running Manjaro.

Thanks.

      I have a USB extender that wont run at any other speed, but its much faster than 2.0 so I would really like to get it working consistently.

          Not sure what you are suggesting… The issue im trying to fix is that this extender only passes 5Gbit/s so if I plug in something that can negotiate up to 10 or lower it will try to configure the lanes that way and the extender will fail.

          The only device I have managed to get working is a USB WD Elements HD. Everything else I have tried that should support 3.0 never connects.

          So I wanted to test to see if I could lock the port at 5Gbit/s to eliminate auto negotiation from my trouble shooting.

    Comment scrubbed. Leaving .world due to corporate-adjacent admins, lack of transparency when making changes, selective rule enforcement and inconsistent rules on piracy.

    Maybe with udev rules? ATTRS{speed} maybe? Lol idk, I’ve never tried to downclock USB speeds.
