> it can say that it’s a controller and it will give the bus address to talk to and a polling rate.

Many moons ago (over 25 years) I was an EE hobbyist working with an inventor, working adjacent to a major game controller manufacturer. The controllers I was prototyping weren't getting polled by the OS. I was just using the USB HID Class and sending "Button Up" and "Button Down" messages using Interrupt Transfers. Are game controllers using Isochronous transfer now or is there some other method that's developed in the last quarter century?
