Solaris 10 update 5 disables USB 2.0 for Belkin USB controller

According to

http://www.sun.com/io_technologies/i...trolers22.html

the Belkin F5U508 USB/Firewire card is "verified" for Solaris 10 on both
SPARC and x86. So today I goes out and buys one, installs it, and it
seems to at least work. But looking in /var/adm/messages I see:

So it is only going to work as USB 1, which is bloody annoying, as I
bought it to give me USB 2.0 in the Blade!


Anyone know what the issue is which have caused Solaris to downgrade the
card from USB 2.0 to USB 1?

I've done that and enabled it, but I'm not 100% confident. Clearly there
is an issue, and its not clear that this work around is totally sound.
