If you go to System in the Control Panel and under the Hardware tab click on "Device Manager", you can see a list of USB hubs ("Universal Serial Bus Controllers").
For each hub listed you can see the power use. Right click on the Hub, then click Properties. Go to the Power tab and you can see a list of devices and the power they've been allocated, as well as the maximum that can be allocated.
Note that you'll see more hubs than you can find on the outside of your PC. My notebook has two USB ports, both on the same hub, but it has 5 listed USB hubs (internal devices, etc.).
This is for XP. Win 2000 is similar. Dunno about Vista.
