Udo,
I am adding the mailing list as there are people who are experts in
this part of the kernel who
known more then me. I am going to explain my trace of this to you and
add it below for
the other developers to read about the issue here.

1.  The first part of the trace is going to vb2_internal_streamoff and
in this function we are calling the second function
of the trace which is vb2_buffer_done.
2. In function ,vb2_buffer_done we have a few WARN ONS and now to we
need to find the correct one
3. Since we are calling the function with the state,
VB2_BUF_STATE_ERROR  we are tracked to the first
if statement here as we are not streaming at this point

if (WARN_ON(vb->state != VB2_BUF_STATE_ACTIVE))
 return;
We will hit your warn on and print out your message. This seems to be
correct at least to me but let's see what the other developers state
about my trace.

As for the other developers on the list seems to a miswritten call
before be are streaming this queue of data and I would recommend
moving the lines

q->streaming = 0;
q->start_streaming_called = 0;
q->queued_count = 0;
before the for loop that calls vb2_buffer_done inside it's self. I am
not sure if this is a correct fix through as I am new but if it is I
will write the patch
and sent it to the usb mailing list.
Regards Nick
