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 .
We can connect two computers over USB and we do it all the time. E.g. your phone and your PC. One or both of the computers needs to be able to act as a device. Most Android computers can switch between host and device depending on what’s plugged in. It all comes down to implementation.
