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?
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.
Connect a 5gbps USB hub to your computer. Now you have a USB port that is limited to 5gbps to connect your extender to.
ahh makes sense, I will see if I can find one!

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.
