So, without USBInjectAll, the number of USB 2.0 ports is limited, and the webcam does not work as it's 2.0.
If I put the kext in /L/E the USB 2.0 ports work perfectly, webcam is seen, but only one USB 3.0 port.
I think it could be a kext patch issue? Attached previous (before the mess up) and current Clover folders for debug.
