  Log:
  The EHCI qTD token has a number of error status bits that are not
  cleared if the host controller retries the transfer and is successful,
  but we were interpreting these bits as indicating a fatal error.
  Ignore these error bits, and instead use the HALTED bit to determine
  if the transfer failed. Also update the USBD_STALLED detection to
  ignore these bits.
