What the USB Port Has Replaced

And nothing to replace it yet

You might not exactly love the USB port, but considering that it replaced two com ports (or more if you ran a BBS), a parallel port, a game port, and assorted PS/2 ports, we might excuse its imperfections. ArsTechnica looks at its history, what came before it and what's waiting with USB Type-C.

Some of these ports required their own dedicated expansion cards, they all took up a bunch of space, and they were often fussy when it came time to configure or troubleshoot them. By the late 90s, computers were starting to come with a couple of USB ports, usually a couple of them on the back of the system—these were usually USB 1.1 ports, capable of speeds up to 12Mbps (or 1.5Mbps for peripherals like keyboards and mice). Accessory makers didn't all make the switch to USB right away, but keyboards, mice, printers, and other accessories began to include USB ports and connectors as an option, then as the primary interface.
