Hi, about missing USB1.1 support in Ventura+, is it possible to install a USB 3.0 PCI express card and use it for keyboard and mouse? I have a MacPro3,1
 
I believe that should work as Ventura has USB 3 drivers. What works for me is using an Apple keyboard (hub) and plugging in my wireless mouse dongle into the keyboard

You may be missing keyboard/mouse in the Startup Manager (hold option key at boot which can't work from USB 3.x unless EFI XHCI driver is loaded). I think OCLP comes with a USB 3 (XHCI) EFI driver so keyboard/mouse works in the OCLP menu?

This works because the keyboard is USB 2.0 and forces the built-in USB of the Mac Pro into USB 2.0 (EHCI) mode instead of USB 1.1 (OHCI) mode.
