Done -- reworded to stand alone without referencing prior versions.

Fair point -- the timeouts were correct for PCIe; USB was not in
scope yet. Changed to "condition" instead of "bug".

You're right, I overclaimed. Reworded to note that transport
round-trip latency appears to dominate under these test conditions,
but hardware and external component factors may also contribute.

All three changes applied in v3. Also added Tested-by tags from
Devin Wittmayer across RTL8922AU/8852AU/8852BU/8852CU (Framework 13
and Raspberry Pi 5), and Reported-by with a link to his xHCI hard
lockup evidence.

Thank you for the review.
