So, yesterday my USB ports suddenly stopped working on my desktop. I thought it was my keyboard at first, but the same thing happens with my mouse. I tried moving my mouse and/or my keyboard to different ports when in it happens. Sometimes it works, sometimes it doesn't. Restarting the computer makes them work again, until they randomly stop yet again. I've tried updating the drivers. I've also turned off the options under USB controllers Power management that allows the computer to turn off the device. Did the same under Human Interface devices. I'm not sure what's going on. Not sure what info you'd need on my specs.

Update your post to include full system hardware specs and OS information.

Include PSU: make, model, wattage, age, condition.

How many USB devices are connected? What are those devices?

Are you using any USB hubs? Are those USB hubs independently powered?
