Jacob Alexander 20b62afb9a FIxing Media Keys and general USB compatibilty 
- Media keys tested working on Linux/Windows/Mac (use Consumer control)
- Fixed enumeration delays
- Fixed virtual serial port configuration issues
- Fixed GET_REPORT and SET_REPORT
- Added intial descriptors and endpoints for Mouse and Joystick devices
- Split out the consumer and system control endpoint
- Added more fault debugging messages
- Added interface names to endpoints (visible in Windows Device Manager)
- Added KLL define for keyboard locale

//
// 50 (ISO \ due to \ bug) and 156 (Clear due to Delete bug) must be excluded
// due to a Linux bug with bitmaps (not useful anyways)
// 165-175 are reserved/unused as well as 222-223 and 232-65535
//
// 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)
// 51-155 : 14 bytes (0x33-0x9B) (105 bits + 6 padding bits for 15 bytes total)

// 176-221 : 6 bytes (0xB0-0xDD) ( 46 bits + 2 padding bits for 6 bytes total)
