cool down buddy!
The ChamsysWings works perfect, if your Wing doesn't work on your laptop without using an external powered usb-hub, then thats a problem of your laptop and your laptops usb-ports are out of the specification!
Working with a MiniWing without an external hub is the normal Operation-Mode here... no problems at all.
And, a good hint, forget Windows Vista. Vista is crap, and no realtime OS with all the bugs. For a really well running system, use either XP Pro SP3 or use the new Windows7. Vista make strange things with some pieces of software! It shouldn't do that, but Vista sometimes make things you can't understand. So, install a Bootmanager on your laptop, install a clean XP Pro SP3 and be happy with your perfect running system.
