Comment (by waddlesplash):

 Debounce and wakeup times do not appear to be any different for USB3 than
 they were previously; at least I don't see any special handling in the
 Linux kernel here for this.

 I do note that there are a variety of TODOs in XHCI::ConfigureEndpoint
 about USB2 vs. USB3 at present, most of which center around fetching the
 companion descriptor and then applying it to various settings. Probably
 that is relevant here.
