Detailed Description

Snapshot of the attached HID device, passed to the attach callback.

Populated by the host-HID driver once the descriptor walk completes. The pipe number is the controller-side handle wired up against the attached device's interrupt-IN endpoint. The recipient should hold onto this struct (or copy it) so subsequent get/set report calls land on the right interface.
