HAL is not used. + * + * Current driver limitations (i.e., a list of features for you to add): + * - STALL handled, but not tested. + * - Does it work? No clue. + * - All EP BTABLE buffers are created based on max packet size of first EP opened with that address. + * - No isochronous endpoints + * - Endpoint index is the ID of the endpoint + * - This means that priority is given to endpoints with lower ID numbers + * - Code is mixing up EP IX with EP ID. Everywhere. + * - Packet buffer memory is copied in the interrupt. + * - This is better for performance, but means interrupts are disabled for longer + * - DMA may be the best choice, but it could also be pushed to the USBD task. + * - No double-buffering + * - No DMA + * - Minimal error handling + * - Perhaps error interrupts should be reported to the stack, or cause a device reset? + * - Assumes a single USB peripheral; I think that no hardware has multiple so this is fine. + * - Add a callback for enabling/disabling the D+ PU on devices without an internal PU. + * - F3 models use three separate interrupts. I think we could only use the LP interrupt for + * everything?
