devcon install driver with Found New Hardware wizard?

I use the devcon to install my driver based on the vhidmini sample in
the DDK.
everything went well except that a Found New Hardware Wizard dialog
appeared
and disappeared later. It would disappear automatically but it’s still
annoying.
How can I get rid of that? My system is XP with sp2

Thanks a lot.

Cheers.
Long
