--- Comment #2 from yan12125 pq2sx44teeigl7za@chyen.cc --- Created attachment 79149 --> http://bugs.winehq.org/attachment.cgi?id=79149 Proof-of-concept patch
One idea is querying the protocol to use if pioSendPci=NULL. Note that this patch was tested with older wine. I'll rebase and retest when I have time.
