ACPI Error on Lenovo AIO A540 Catalina + OpenCore 0.6.2

Hi All,

I'm trying to get my Lenovo All-In-One A540 to boot the Catalina installer.

Following the guides on Dortania, I've built the config (File structure and Config.plist)
I've built the DDSTs from SSDTTime.

Upon boot, I'm getting an ACPI Error for \_SB.PCI0.XHC_.RHUB.SSP3.

I can't find this in Windows, and although I've spent a fair few hours reading up on ACPI and it's language, I'm trying to figure out how to resolve this.

Whilst I'd really appreciate a fix here, could someone tell me: Does the error mean the OS cannot find SSP3? Or is it that it is referenced in the System's DSDT and the OS does not understand it, and it needs to be patched? \_SB.PCI0.XHC_.RHUB is referenced in the USB_Reset.aml
