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 .
In general, because what everyone thinks of when they say USB is a host-device protocol, and you’re trying to connect two hosts together.
But USB is a blanket term for a number of protocols, and there are protocols that allow a host to switch roles and become a device, depending on what it’s connected to.
If you see a PC being advertised with “dual role USB ports” or support for “USB-OTG”, then you can connect it to another PC. Otherwise, you almost certainly can’t.
If all you want to do is transfer files, you can use something like QuickDAV to transfer files over your local network.
