I'm trying to create a composite USB device with 3 CDC VCOMs. The code is hard-faulting when the USB IRQ Handler goes to the ISR. Everything looks good when bringing up the USB configuration with the USB ROM.
/******************************************/
/* Function Name: usb_cdc_connect */
/* Return Type: ErrorCode_t */
/* gets the parameters, creates the */
/* handles, registers the endpoints IRQs, */

ret = USBD_API->cdc->init(g_hUsb, &cdcParameters[0], &g_hCDC[0]);
PRINTF("Initializing first CDC...");
result = (LPC_OK == ret);
PRINTF(result ? "Successful\r\n" : "Failure\r\n");

Hello @dean_sands
1) First method is debug step by step check issue.
2)Recommend use Config tool inside MCUXpresso IDE to config. Can refer to:
