+ // 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)
