R7 6800H, RX6850M laptops having USB issues while installing Sonoma

[zxc2689963]

Hello, I recently tried to install MACOS on a laptop model: Legion 7 Gen 7. It has a RX6850M XT graphics card. Thanks to the NootRX project, it can run successfully. I encountered a USB non-recognition problem during the installation. It may be The reason why the USB controller bus is slow is not identified. I have tried booting the system to the hard disk without any USB-related kext. The performance is that the keyboard and mouse are very slow. It takes a long time for keyboard input to respond, and it takes a long time for the mouse to move. I used many methods to customize the USB port. Finally, I used the old version of GenericUSBXHCI. kext to start the system on the hard disk. At this time, the keyboard and mouse were normal, but the USB storage function was invalid. It was the same as the Legion 5, but not exactly the same. Does anyone know? Any idea how to solve it?

Did you make USB mouse and keyboard normal. Or you make track pad and internal keyboard normal? What change did you make after installation? Just replacing GenericUSBXHCI. kext with the old version? How long did you install from USB? My USB took 3 hr to boot on the installation page because of the broken USB issue. Is it possible to complete installation in reasonable time?

EFI Any updates ?I got the similar laptop

Any updates ?

After several days of constant trying, it still failed. I think this may be a USB4 compatibility issue. Most USB controllers of the R7 6000 CPU are based on USB4. I saw such as HX99G and Legion slim 7 Gen 7 (RX6600S 6800S ) all have the same situation. There is a special GA402 controller that is not based on USB4. It seems that this cannot be solved in a short time, unless the RDNA2 architecture core display can be successful and more people join.
