My PC has several 3.0 and 2.0 USB ports. What's the basic difference and give me examples of devices which should be connected to each type port.

USB 3.0 is backwards compatible to USB 2.0 so it doesn't matter if you hook a device for 2.0 into 3.0. Right now there are few devices that use USB 3.0 Mainly only flash drives and external hard drives do, those you should hook up to 3.0. Otherwise it is indifferent.

USB 3.0 has a faster transfer rate than USB2.0 BUT the only things that can take advantage of it at this time, are some external hard drives and some USB flash drives.
Some external HD/USB drives require USB 3.0 only, but anything else can be plugged into either a 2.0 or 3.0 socket with no problems.
