Ask HN: Advice for creating a USB device linking 2 computers
I want to build a little device that connects two computers together via usb, and send keystrokes from one to the other. (I would use it to use a laptop keyboard on a headless computers). I am looking for an easy solution, it does not have to be the cheapest. ChatGPT points me to Arduino, but as far as I can see, there's no arduino with 2 usb ports. It also points me to Raspery pi zero, but that's a computer, not a microcontroller, so not sure if it's suitable. If anyone with experience can give me some pointers, it would be greatly appreciated! 15 comments on Hacker News.
