Anyone not living under the rock for the last decades uses libusb. No need for special permissions at all, you can even use WebUSB in browsers these days.
All you need is competent firmware and driver engineers.

I used libusb for my laptop's keyboard LED driver and it absolutely does require root access. At least it works instantly and exits afterwards, unlike the manufacturer's shitty app.
