Big Sur open core no usb wlan

I was running Catalina on the machine (Haswell) flawlessly expect for embedded wi fi which was not supported. I was using an external usb. Decided to make the jump and installer Big Sur with open core. All went well but Strangely none of my usb wi fi are detected, even after installing drivers. The light on the usb device doesn’t even come on. Any ideas?
