OK, that's perfect, thanks.

<speculation>
  Maybe it's for the situation where you have a case with a built-in 
  USB port (or ports) but the motherboard doesn't have on-board USB?

Actually, if it worked on 5.0-RELEASE, that's probably close enough.
It'd be interesting to see at some point if 5.1-RELEASE probes the card 
as a USB 2.0 device (it should).

OK.  I'm probably going to defer this until after 5.1-RELEASE.  (I'm
trying to reduce the churn in the release documentation because this
creates last-minute work for the translation teams.)  I can do this
anytime after the release though.  If you don't see this go in within a
week or two after the release, can you send me a ping?  (Alternatively,
file a doc PR and send me the number.)

Thanks!

Bruce.
