From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

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 .

Universal Serial Bus.

Serial communication between two hosts requires either robust auto negotiation or a crossover cable.

Usb doesn’t have good auto negotiation between two hosts so you gotta use a crossover cable.

heres one

But… there’s no guarantee that the computers usb controllers and operating systems will support it.

Most modern NICs will auto negotiate now so the cross over cable is no longer needed.

Yeah but like if instead of usb it was a db9 you’d need the tx and rx crossed over.

That was called a uh null modem back in the day

Would be nice to have a date on that statement in the product description. Seems to be outdated?

Oh no, they say right there that it will not let two computers connect to each other lol.
