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 .
And it was a good design - it’s universal (aha) adoption proves that.
Those of us old enough to remember the pain of using 9 and 25 pin serial leads and having to manually set baud rate and protocols, along with LPT and external SCSI and manufacturer specific sockets probably agree this was a problem that needed solving, and USB did do that.
