My hardware has different buffers for each endpoint. As I understand
you, the host try to send a setup packet 8 bytes AND a 24 bytes packet
to another (bulk) endpoint. But why wireshark could not see the two
packets? I could believe that my hardware do mysterious things and my
driver also, but how could the tracer show the things in that way?

I maybe have Monday the chance to look directly on the bus with a
hardware tracer. Maybe this clears the fog a bit :-)

Thanks
 Klaus
