Mouse, keyboard, digital cameras, camcorders, screens, data memories, MP3 player and other devices can be connected to the computer via the USB interface. The USB interface is used more and more in television devices or DVD recorders. The USB 2.0 specification with 480 Mbits/s offers noticeable higher transfer rates as USB 1.1 (12 Mbit/s and 1.5 Mbit/s). The cables and plug-in connections remain the same in order to guarantee full compatibility to USB 1.1. Every USB 1.1 device can be connected to a USB 2.0 interface. On the other hand, a USB 2.0 device can be connected to any USB 1.1 interface. The data rate always conforms with the slowest device.
