usbd auto stall control for not supported return from class control request
usbd implement xfer isr callback mechanism
DCD
- implement dcd multiple qtd support
- dcd dcd_pipe_stall
- implement dcd_pipe_queue_xfer
- xfer_complete_isr
- flush control endpoint if received new setup while previous transfer is not complete
change msc_cmd_block_wrapper_t flags field to dir
force full speed for easy testing
NOTEs: somehow unable to get endpoint IN interrupt with ioc
implementing dcd_lpc175x_6x.c
add usbd_dcd.h
add usbd_isr with TUSB_EVENT_SETUP_RECEIVED & TUSB_EVENT_BUS_RESET event
parameterize TUSB_CFG_DEVICE_CONTROL_PACKET_SIZE (replace USB_MAX_PACKET0)
--> able to get interrupt and receive setup packet, but SET ADDRESS (expected get device descriptor).
uncomment write zero length will cause issue, no more interrupt ?
