https://forum.amd-osx.com/threads/amd-rayon-r7-6800h-install-ventura-kernel-panic.4639/page-2#post-35426 Do you have the same brand with mine? If your laptop is the same with mine, you can go to this thread and work together with us

I have tried switching USB port after SMCprocessorAMD text, but it still gets a forbidden icon, you can merely see a text showing USBSMC identifier non-unique

Using the old version of GenericUSBXHCI.kext seems not working. It would get a forbidden icon SMCProcessorAMD. Next I will try generating UTBMap.kext to see whether it works

Thanks for your reply, I will create UTBMap.kext in linux to see whether it works.

Thanks for your reply,I think I have tried every USB port on the laptop but the issue is still the same

Would you help me check out my issue? Thanks
