Which chip is responsible for the tactile screen, USB, camera and SD-reader in Lenovo Flex 3?

Question

laptops

The other day I bought a Lenovo Flex 3 laptop.
Before loading Windows, USB ports, an SD-reader work (the tactile screen and the camera cannot be checked in the BIOS).
As soon as the system starts to boot, the USB ports, the card reader stop working, the touch screen and the camera do not work (in the task manager it says that the XHCI Universal Bus cannot start - the device cannot be started, error code 10). I tried all the solutions I found on the net, but it looks like a hardware problem.
The question is - which chip is responsible for the operation of the tactile screen, USB, camera and SD-reader?

Answer 1

Driver "south bridge" of the motherboard or USB controller.

Answer 2

100% driver problem. I would recommend reinstalling the system and installing original drivers from the Lenovo website, I'm sure everything will work
