I haven't tried a bluetooth device in years, is pairing still godawful? I wish they would give you the option to pair through USB. Just plug in the host and peripheral and press the pair button, and it should automatically negotiate pairing. I don't care if it requires the hassle of occasionally having to plug something in to pair the two devices as long as it works 100% reliably.

AFAIK, there isn't any official USB protocol for this, and I think there really should be. Pairing has to be out-of-band to be properly secure against MITM attacks during pairing, and using USB would be such a simple way to achieve that.

Apple has a proprietary USB protocol for pairing its own wireless keyboards, trackpad and mouse, and Microsoft and Sony have proprietary protocols for their respective gamepads.

I don't think Xbox uses Bluetooth for their gamepads. It's some proprietary protocol over 2.4Ghz as far as I'm aware.

Recent Xbox controllers support both Bluetooth and a proprietary protocol; Microsoft sells an optional dongle to use the latter on PC.

AFAIK, PlayStation wireless controllers are Bluetooth-only, but the DualSense (PS5) controllers use some proprietary extension not supported on Windows for haptic feedback over wireless that's sent via standard audio protocols over USB.
