/* Endpoint API
* Note:
* - Address of control endpoint OUT is 0x00, In is 0x80
* - When stalling control endpoint both control OUT and IN must be stalled
* (according to USB spec, stalled control is only recovered with setup token)
* - open : Configure endpoint's registers
* - xfer : Submit a transfer. When complete dcd_event_xfer_complete
* must be called to notify the stack
* - busy : Check if endpoint transferring is complete (TODO remove)
* - stall : stall ep. When control endpoint (addr = 0) is stalled,
* both direction (IN & OUT) of control ep must be stalled.
* - clear_stall : clear stall
* - stalled : check if stalled ( TODO remove )
