The WeDo USB hub has 2 I/O ports. These can be connected to WeDo sensors or Power Functions Motors.
The hub can only provide 5V to motors, so they will not be as powerful as if you were using a proper Power Functions battery. You also need to be careful not to overload your USB port. Most ports are limited to 500mA per the USB specification. However, the EV3 will supply up to 1A.
