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 .
You actually can connect a Steam Deck to another PC. Look for the DeckMTP plugin on Decky Loader.
MTP is the thing Android uses when you connect your phone to a PC. It should be possible to install on any PC. Don’t know about Windows but there’s probably a solution for that as well.
Don’t know what happens when both devices have it. I’d suspect that they would both be able to access each other’s drive.
