Year futuretech, you'r great

The article fixed all my problems.
So the sollution is:
If Vista normaly have a driver build in and cannot find it and ask for a driver disk point to:
C:\Windows\System32\DriverStore\FileRepository
and then Vista can find the driver.
Works with my USB memory stick and my DV camera via Firewire.
....but now still I have the question why Vista is not looking at this folder for itself? Why I have to point to the folder? (yes I really want to understand Vista..... )
