   Hi, XHCI disabled mode for cpu lanes does not work. USB is still full speed, should be usb 2. This mode works for chipset.

Please look into it.

/Thanks

	Ok i solved myself, found the correct setting. So the "global" XCHI setting doesnt do it, but this setting seems to turn chiplet usb 3 to usb 2, but not cpu lanes usb ports. For that we need to disabled following: Advanced\AMD CBS\FCH Common Options\USB Configuration Options .. then turn USB 3 to disabled. Then cpu lane usb 3 turn into usb 2.
