There is a potential problem when cameras are connected through USB hubs. Some cameras can demand a lot of power and if the hub isn't a powered hub or not capable of powering all of the devices connected to it, it can cause power surge reversal which blows the USB port on the camera and possibly additional circuitry in the camera.

I always connect my camera directly to the PC but for those that use hubs, make sure they are powered hubs and can deliver the required power to all devices plugged in.
