mods are asleep, post the USB specification for the HID identifier classifying a device as a USB magic carpet

1. A table of "5.7 Miscellaneous Simulation Devices". Usage name is "Magic Carpet simulation device" and description is "Description Allows a device to be generally classified as one that uses the standard control of a magic carpet. This control is a bar, grasped by both hands, that controls the Yaw, Pitch and Roll of the carpet. The bar, at which the pilot sits, may be pushed forward or pulled back to cause the carpet to dive or rise, respectively. In the zero position, the carpet is in level flight. Pushing forward on the bar causes the carpet to nose down and generates negative values. Pulling back on the bar causes the carpet to nose up and generates positive values. Turning the bar turns the carpet. In the zero position, the carpet travels straight ahead. Pulling back on the right side turns the carpet to the right and generates positive values. Pulling back on the left side turns the carpet to the left and generates negative values. Rotating the bar rolls the carpet. In the zero position, the carpet travels level. Rotating the bar in a clockwise direction rolls the carpet to the right and generates positive values. Rotating the bar in the counterclockwise direction rolls the carpet to the left and generates negative values."

  @lazerwalker Yeah, I noticed that reading the spec... Never heard of such a device before!

  @lazerwalker I like how the USB HID spec attempted to cover every weird device anyone had ever built that interfaces with humans. I wonder if some of these have never actually been used, since the only devices that would use them predated USB, and no one particularly thought it worthwhile to recreate.
