// Reversing notes
// Tristan Hume
// trying to figure out what packets to send to get the lights to turn on for a TheEyeTribe tracker
// Steps so far:
// debug the server so I can figure out how to log all UVC control requests sent using
// the mechanism in https://github.com/HBehrens/CamHolderApp/blob/master/CamHolderApp%2FUVCCameraControl.h
// I've managed to figure out where the IOUSBDevRequestDesc is in registers at one point
// Next step is to create a debugger script that logs it whenever that method is called.

	// trying to figure out what packets to send to get the lights to turn on for a TheEyeTribe tracker
	// Steps so far:
	// debug the server so I can figure out how to log all UVC control requests sent using
	// the mechanism in https://github.com/HBehrens/CamHolderApp/blob/master/CamHolderApp%2FUVCCameraControl.h
	// I've managed to figure out where the IOUSBDevRequestDesc is in registers at one point
	// Next step is to create a debugger script that logs it whenever that method is called.
