- R0b0t1 6y agoI've definitely seen it. Reusing HID is kind of clever, but the protocol is extremely bloated and hard to parse. Ignoring that, I'm not sure it's an improvement. Most of the power savings is having the keyboard initiate an interruptible event to wake the computer. Interpreting HID like in USB means the keyboard can't wake the computer, the computer needs to remain on to service USB interrupt endpoints.
