5k+ USB Malfunciton

I am running into an issue where my 5k+ LED is red and windows says the USB device I plugged in malfunctioned and windows cannot recognise it. PiTool thinks it isn’t connected at all (Saying DP/USB cables are unplugged and the application integrity is incomplete, despite reinstalling different versions of PiTool several times.) In device manager it is showing up as an unknown USB device (Device descriptor request failed). I am having all sorts of problems with my headset, how do I get around this?

I have had that come up from time to time. Typically for me a restart or shutdown cold restart has usually corrected it.

Though might be an idea to file a ticket.

Which USB are you using? (2,3,3.1,C)
Onboard or PCIe Card?
As I am someone using loads of USB devices at my studio I can tell that for miracolous reasons USB power and bandwidth seems to shift from time to time, even when not adding more devices.
I can‘t put a finger on that, but it may be the case due to all kind of power saving modes play together.
On my old board installing an extra sata powered USB PCIe card solved all issues.
So you have an independent source for usb that is not affected by other usb ports.
My recent board seems fine in this regard.
It‘s not a guarantee that it will help you but it’s a good starting point. You may look into it.

I’m using onboard 2.0 and 3.0, I keep switching to see if it works.
I don’t have many devices plugged in, only mouse, keyboard, pimax and a Bluetooth adapter.

It does not necessarily mean that the amount of devices count. I was just hinting that this phenomena does exist. With my old board even unplugging everything else did not solve it. I had to go for an additional PCIe card.
There are more things involved.
Even a simple case front panel extension cord can suck up the deciding headroom for your usb device. It may go unnoticed on the majority of devices.
Other users reported that they could fix it via bios, as some boards provide a power boost for certain usb ports (actually intended to improve charging for certain devices). I tried that on an friends PC and it indeed worked, not so on my old MB though. That may worth a shot as well, check your bios.

Maybe post your mobo brand and model.

Is your motherboard bios and chipset drivers up t9 date? Not relying on Windows update.

I updated the usb drivers via windows update and have had no problems on that computer. On my other computer, however, SteamVR thinks the headset is asleep and I cant get the headset to wake. I’ve tried moving it around, tipping it upside down, reopening SteamVR, but the screen is still frozen on the headset

Try using the Motherboard’s website. As @Enopho has said often windows will choose incorrect drivers for a variety of things. Using a more generic driver.
