@JirehLB ASUS are not interested in helping and other than here AMD seem to have no point of contact.
I can get my laptop to see the USB 2 device if I trick it but I am not sure what this proves. Allow me to explain.
As standard the USB 2 device doesn't work in any of the USB ports, either the 'dedicated' USB 2 port from the 5600H CPU or the USB 3.1 ports.
If I plug in an external hub magic happens. The USB 2 device is then seen and works perfectly in the hub and also in all the laptop ports. Unplug the hub and the connection to the USB 2 device drops immediately.
Clearly the AMD USB 3.10 eXtensible Host Controller can talk to USB 2 devices but why you have to plug in a hub to make this happen I don't know.
It is obvious as I type this that this is an AMD issue but can it be fixed with software or is it bad hardware?
Try yours with an external hub and let me know. Good luck.
