While trying to troubleshoot VR Compatibilty (Vive HTC Pro, tried with Envision & SteamVR), mainly the audio being completely borked and steamvr crashing after a few minutes, I noticed that, while checking for USB Bus overuse, that every device of the Headset (Camera, HMD, HID, Audio, etc.) was all on one singular bus, obviously overloading it
There’s seemingly no workaround to this, other than buying an external PCIe expansion card.
Here’s the output of lsusb -t:

Any possible fixes, I will try (except sudo rm -rf /)
Please help </3
(Second edit was changing the lsusb -t output, I had pasted one with the Link Box disconnected on accident, so now it’s correct
