USB3 does not work

[andy5411]

I bought a z240 made in 2014. It arrived without an operating system. I installed Windows 10 enterprise. I updated Bios and downloaded the HP drivers.
Two things don't work:
Intel (R) 82579LM Gigabit Network Connection.
This is a minor problem because I can use it with a USB-WIFI adapter.
The big problem is that the USB3 ports don’t work. Neither the front nor the rear. All USB ports are enabled in Bios. There is no error with USB controllers in Device Manager, but I don't see a USB3 root entry.
I'd like help
