I'd suggest "supports USB 2.0-compliant full-speed devices" instead.

And before you assume that high-speed devices (flash drives, wlan, etc)
don't work correctly because of something your driver does I would
strongly recommend to perform the same tests using another full-speed
HC, e.g. by using uhci_hcd as the only hcd, disabling ehci_hcd, on
EHCI hardware.

I've seen high-speed-capable devices work quite poorly at full-speed;
who cares about correctness when there is performance?
