Keyboards from the late 90s and early 2000s often did something similar. The controller supported both PS/2 and USB and the keyboard would come with a PS/2 plug and a passive adapter. That's why if you're trying to use a PS/2 keyboard designed prior to the introduction of USB (like a Model M) on a modern computer, you need to make sure to get an active PS/2 to USB adapter that actually translates the protocol.
Yeah, I discovered this the hard way when I tried to plug a somewhat modern keyboard to a pc through ps/2 (for the theoretical interrupt-driven speed) and didn't work.
A lot of mechanical gaming keyboards still support ps/2 though for the aforementioned interrupts.
You'd see playback issues go up by 1000%.
