Piggy-backing this comment to add some context for the OP video: This "USB device discovery" video is actually the latest in a series of videos where Ben Eater is building a simple 8-bit computer on breadboards. He hooked up a PS/2 keyboard as an input device, and then got sucked into a tangent of investigating and explaining keyboard protocols.

- He investigates the PS/2 keyboard protocol: https://www.youtube.com/watch?v=7aXbh9VUB3U

- Somebody on Patreon asked about USB keyboards having higher latency than PS/2, so he made a video about the basic USB protocol: https://www.youtube.com/watch?v=wdgULBpRoXk

- He made the OP video about USB keyboards being limited to holding six keys at once.

Whatever happened to wire wrap?

I can understand BBs for quick prototyping and tinkering, but once you've settled on the design, I'd think WW would be less fragile to deal with.
