Lenovo m720q / Big Sur - Only 1 working USB port

I was able to get Big Sur installed and running on a Lenovo m720q, it boots and functions OK. all the iServices run and it sleeps and reboots without issue.

My one big concern right now is that only 1 USB 2.0 port works. I was able to boot and install from a different USB port but it was horribly slow to the point that moving the mouse was like downloading a picture in the late 90s.

I looked into USBMapping using Hackintool and USBInjectAll.kext but when I look in the USB section of Hackintool and plug in a device to a USB port nothing changes on the screen like it simply doesn't recognize or acknowledge the ports at all.
