Is the device working properly? If so, I wouldn't be too worried. The
check is that the DMA descriptor whose sub list descriptors we are about
to free isn't enabled. That isn't a problem as long as the DMA isn't
actually working on those particular descriptors (which it shouldn't be,
because we are only allocating descriptors for one urb at a time;
there's no queueing).
I have seen this error message occasionally before, but never as
consistently as in your case, so there might be more to it than I see at
this point. Try define USB_DEBUG_CTRL and add the following line
at line 2057 (just after the dbg_ctrl("Adding ctrl urb...") line and
send the output.
