My new mobo has USB 3.0 and USB 2.0. I haven't seen any USB 3.0 devices yet. Can you use the USB 3.0 jack with a USB 2.0 device? What is the difference? What are the advantages of USB 3.0?

Yes, you can plug in a USB2.0 device into a USB 3.0 port using a USB 2.0 cable, since it's backwards compatible. But obviously you will not get USB 3.0 speeds unless the device itself is USB3.0 and you use the USB 3.0 cable (which has an additional internal physical contact IIRC).

The advantages of USB 3.0 are speed (theoretically 5 Gbps vs 480 Mbps) and supposedly the ability to supply higher electrical power to a connected device.

My motherboard has 2 USB 3.0 slots, but I don't have any device to connect to them lol.
