So i tried to connect steamdeck to pc using usb and i read its immpossible because steamdeck is a computer and some explanation on quora about strong master slave relationship. But then why is it possible for android phones to connect to pc whilist also having the ability to use USB and other usb c accesories. Also why cant it be a toggle? So that you can change whetewer this usb( or device ) is reciving data ot sending data .
Most modern Intel chipsets support “Dual Role Device” (DRD) where they can act as host or client as needed.
And if you want to get really funky, Intel also does their JTAG over USB. They are quite secretive about it, your bios should have turned it off, but it is there.
