Daniel Prilik e6fa6845fe haptics!
https://docs.microsoft.com/en-us/windows-hardware/design/component-guidelines/radial-controller-protocol-implementation

With a little bit of trial and error (and a crash-course in how the heck
HID even works), I figured out how to get the dial to provide haptic
feedback!

Along the way, I also learned that you can take advantage of the
(incorrectly named) Resolution Multiplier field to customize how many
"steps" the dial should have, offloading the work to the device itself!

Very cool!!
