USB_HOST Applikation URB-States

Is there an overview with all possible URB-states that are returned by the USB_Host function "USBH_LL_GetURBState(>>Bulk-In-Pipe<<)"

I figured out some of these, but not all of them:

  • URB_IDLE
  • URB_DONE - Answer received
  • URB_NOTREADY - NAK received
  • URB_NYET
  • URB_ERROR
  • URB_STALL - STAL received

If someone culd help me with the remaining three states it would help my work significantly.

(And yes I know that URB_ERROR indicates an error of some kind, but is it possible to guess what kind of error?)
