Lenovo Yoga 14 (20 FY) USB 3.0 not working

I recently downgraded from Windows 10 to a Windows 7 operating system. When I downgraded I needed to disable secure boot and disable OS Optimized settings in the BIOS in order to boot from the USB drive to install Windows 7.

 

When I reinstalled Windows 7 I did a clean install, put in my Windows 7 Key and installed all the necessary drivers. However, it seems that my USB 3.0 ports are not working. On the flip side, when I plug in my phone or a thumb drive into the USB ports, these devices are recognized in the BIOS. Also, I looked in the device drivers and it seems that my USB drivers are installed.

 

There is, however, an unknown device, which in the details tab reads:

IUSB3\ROOT_HUB30&VID_8086&PID_9D2F&REV_0021&SID_504C17AA
IUSB3\ROOT_HUB30&VID_8086&PID_9D2F&REV_0021
IUSB3\ROOT_HUB30&VID_8086&PID_9D2F

 

Attempted solutions: I tried to reset all BIOS settings back to factory settings but when I did that my OS would not start until I turned secure boot and OS Optimized Settings back off. Also I tried looking for drivers on the website but  could not find any to do with the USB 3.0 ports.

 

Looking forward to any advice anyone can provide in me fixing this issues.
