Hi,
I modiy the usbd_hid_generic example to tow endpoint by sdk15.0.When i use the USB testtool send some datas to usb deivce,the datas cannot be read properly by NRF_USBD_EP_OK status.
code:
static ret_code_t endpoint_out_event_handler(app_usbd_class_inst_t const * p_inst,
app_usbd_hid_inst_t const * p_hinst,
app_usbd_hid_ctx_t * p_hid_ctx,
app_usbd_complex_evt_t const * p_event)
{
if (p_hinst->p_hid_methods->ep_transfer_out == NULL)
{
return NRF_ERROR_NOT_SUPPORTED;
}
NRF_LOG_INFO("ep out status: %d",p_event->drv_evt.data.eptransfer.status);
if (p_event->drv_evt.data.eptransfer.status == NRF_USBD_EP_OK)
{
/* Notify user about last successful transfer. */
user_event_handler(p_inst, p_hinst, APP_USBD_HID_USER_EVT_OUT_REPORT_READY);
}
return p_hinst->p_hid_methods->ep_transfer_out(p_inst);
}
