Blocking USB

I have been tasked with finding a way to block some devices from being
connected to USB ports. We need to be able to block thumb drives for
example, but allow other things like keyboards and mice. I have
downloaded and am evaluating DeviceWall and SecureWave, but am just
wondering what else other people are using and also if Vista will be
able to do this when it is (finally) released.

Thank you
