So OpenCore has a [guide|168466|known issue with USB 1.1|stepid=359059]. The core of it is that Apple dropped all support for USB 1.1, and as you've experienced, it affects any pre-2009 Mac attempting to run anything past macOS 13. From what I could find, the only workaround for this issue is to buy a USB 2.0 hub and connect an external mouse and keyboard to install macOS. This should allow you to eventually run root patching.
