You realize that you are making quite a big assumption with no evidence by saying "I have a usb problem"?
You are not acting rationally. You talk about it, but I don't see you doing any real troubleshooting and all I see is useless crying in a manner of "thingy not worky, me sad".

Let me spoonfeed you the steps.
1. Close everything on your PC, besides steamvr, oculus service, oculus debug menu.
2. Set the resolution to the minium and refresh rate to 120hz
3. Get a well written game which uses OpenXR (Ancient Dungeon fits well here)
4. In Oculus Debug Tool, set Visible HUD to Performance.
5. Start the link and open the game.
6. Move around in the main menu, move your hands and check your latency numbers.
7. Switch Performance HUD from Performance Summary to Oculus Link Detail, check stability of the transfer graphs and write the numbers down.
8. Close the game and start increasing the resolution, test and write the numbers down.
9. Go to step one, but now use air link through the dedicated wifi6 asus router
10. Compare the numbers of air vs cable
 
Stop making assumptions based on nothing and trying to "fix" the issues you don't even know exist for sure. That is just stupid and if you do so, you deserve to be talked to in the condescending manner. 
That's all.
