Fair point -- the timeouts were correct for PCIe; USB was not in scope yet. Changed to "condition" instead of "bug". > I'm also not sure if this is correct.

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.
