From your description it sounds like you plugged all the USB devices into your hub, then plugged the hub in to your machine.  A good place to start with this would be to go into device manager and remove everything.  Then plug in the hub by itself and wait for Windows to load the drivers.  After that plug in each device individually and load the software for each. Follow the instructions that came with each device, because it is important with most USB devices that you load the USB software before you load the drivers.  Leave the devices plugged into the outlet you loaded each one on, as they won't run on a different plug without reinstallation. Some Belkin mini hubs don't supply enough power to run certain devices, and you will need to plug in the AC adapter.  Just to eliminate that as a potential source of this problem, run the mini-hub off the AC adapter right away to see if you have this problem again.
