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!

I believe the search keyword for what you're looking for is probably "IP KVM".

You know, looking back at this eight hours later, I realize that this post sounds way worse than I intended. I was attempting to signal my own epistemic uncertainty, not imply sarcastic dismissal. Sorry. :/

No problem at all, I didn't interpret it as sarcastic.
