Hello,
the wireshark-created link to corresponding isochronous transfer packet in
display of dissected packet probably ignores the "IRP ID" field; instead, the
direct neighbour by time is pointed to (last request before the response, first
response after the request).
In the attached example, no link to response is displayed in the first 7
packets (requests); in packet 8 (request), the link is present but points to
the immediately following response (packet 9) which is actually a response to
packet 1. The same happens in reverse direction, the link to request in packet
9 points to packet 8 while it should point to packet 1.
Thank you
Pavel
