	// Compatibility Notes:
 | 
						|
	//  - Using a second endpoint for a boot mode device helps with compatibility
 | 
						|
	//  - DO NOT use Padding in the descriptor for bitfields
 | 
						|
	//    (Mac OSX silently fails... Windows/Linux work correctly)
 | 
						|
	//  - DO NOT use Report IDs, Windows 8.1 will not update keyboard correctly (modifiers disappear)
 | 
						|
	//    (all other OSs, including OSX work fine...)
 | 
						|
	//    (you can use them *iff* you only have 1 per collection)
 | 
						|
	//  - Mac OSX and Windows 8.1 are extremely picky about padding
 | 
						|
	//
 | 
						|
	// Packing of bitmaps are as follows:
 | 
						|
	//   4-49  :  6 bytes (0x04-0x31) ( 46 bits + 2 padding bits for 6 bytes total)
