Hello, i've been having trouble with my hardware, on a lenovo legion 5. Keyboard, mouses, don't work, but small things like a usb flash works perfectly, even my phone charging works very slowly, i also tried an old mouse with leds and they had light but didnt get recognized by windows and thus didn't work. I suspect the usb ports aren't getting the energy they should've i don't what kind of fix i can do but any help would be very helpfull, thank you.

My lenovo has been having problems with usb connections, especially the ones located on the back, yesterday the usb ports on the back stopped working completely while other ports like the hdmi or even the charger still works, the usb port on the side also works, i managed to fix it by unnistaling the ACPI UCM-USCI and restarting the laptop, unfortunately after a while the usb ports stop working again, i already did sfc scan now, check the drivers, hard reset, and checked the motherboard, there is on signs of burned or debris. I don't know what is making this happen, if anyone has been having similar problems or know the solution i would be very thankfull
