Down clock USB 3.1 to 5 Gbit/s

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.

Why?
- 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.
  
  The hub is malfunctioning then. USB devices register themselves and there capabilities on the bus.
  
  Have you tried using it with a hub that only supports 5gbps?
Sounds like chicken and the egg problem. Speeds are based on what the device supports.
Maybe with udev rules? ATTRS{speed} maybe? Lol idk, I've never tried to downclock USB speeds.
