USB Issues with Mac Pro 5.1 Sonoma 14.7.6 OCLP 2.4.0

Hi all, I'm having issues with the USB ports on my 2010 cMP 5.1. Around the time I upgraded to OCLP 2.4.0 (root patches are applied), all in-built USB ports have started acting strangely. They:

- Do not recognise connected mouse/keyboard/MIDI controllers in the USB tree or accept input.

- Do recognise and interact with USB thumb drives (3.0 and 2.0)

- Do provide power.

Internal USB 3.0 PCIe card works fine.

I am trying to figure out if this is a bug from OCLP's side, or a failed USB controller on the back plane board. I know that USB 1.1 support is provided by OCLP only, hence why I am thinking this is a bug in the latest OCLP version. Anyone experiencing something similar?
