What is USB 2.0?
Finalized in 2001, USB 2.0 is the next generation peripheral connection for personal computers. USB 2.0 allows much higher speeds than the older USB1.0 or USB1.1. USB Hi-Speed is another name for USB 2.0.

USB 1,0 refers to the first design specification for USB drives. The following specifications are USB1.1 and USB 2.0. USB 1.1 allowed a maximum transfer rate of 12Mbits/second. USB2.0 devices signals are transferred at a maximum rate of 480Mb/second. USB 2.0 specification incorporates three speeds: Hi-Speed, Full-Speed and Low-Speed. So a USB2.0 product will function with system requiring USB 1.0 or 1.1.

No. It will only run at its basic speed.
|
Because of the high speed of USB2.0, it will be widely used on high bandwidth devices such as digital cameras, web cameras, flash card reader and other high-capacity storage systems.
|
There are some devices operates at slower speeds. They do not need fast data-transfer rates. So consider the cost, those devices will still use USB 1.1. These include: mice, keyboard, joysticks and audio speakers.
