- //
- // 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)
