| steeven | 55:7c559fcb1d17 | 3 | !!! only tested CDC on LPC1768 |
| steeven | 55:7c559fcb1d17 | 4 | TODO: |
| steeven | 55:7c559fcb1d17 | 5 | 0. need to associate max packet length with endpoint |
| steeven | 55:7c559fcb1d17 | 6 | 1. Rework HID |
| steeven | 55:7c559fcb1d17 | 7 | 2. test Composite |
| steeven | 55:7c559fcb1d17 | 8 | 3. rework device... |
| steeven | 55:7c559fcb1d17 | 9 | 4. rework all HAL drivers |

| steeven | 55:7c559fcb1d17 | 11 | Why not direct extend to USBDevice? |
| steeven | 55:7c559fcb1d17 | 12 | USBDevice has to be shared to multiple interfaces of a composite device |
| steeven | 55:7c559fcb1d17 | 13 | Why not multi-extend? |
| steeven | 55:7c559fcb1d17 | 14 | Some time need to implement 2 CDC or HIDs, can't extend twoice |
