Another problem I'm struggling with is that the ports on my two ASM2142 controllers (front and rear) is inconsistent and shows up with the wrong connector mapping. When the mapping is correct (Se attached picture) sleep and extended sleep is working. When it's wrong I had occasionally crashes depending on Kernel panic, NMI issues. This extended sleep crashes is due to mismatched ports and I can’t do anything about it. My USBMap.kext is correct (@corpnewt). There is no support for ASM2142 USB 3.1 Host Controller in Big Sur so I have to use a kext provided from @apfelnico and I’m not sure this kext is working as it should.
