A 2.0 device identifies itself as a full speed device at first then negotiates with the controller via a series of chirps. The 1.0 version can only recognize low speed and full speed devices.

USB 2.0 must have backwards compatibility with 1.0 which means that even if you have a 2.0 USB port, you can still stick your USB 1.0 keyboard on it and it would work perfectly. USB 2.0, which is an upgraded version, adds the high speed connection to the previous two standards and results in 480Mbps theoretical throughput. During initialization, a connecting device is identified as low speed device or full speed device. USB 1.0 can either be a low speed device which runs at 1.5mbps or a full speed device at 12Mbps.

The very first standard of USB 1.0 provided only 1.5Mbps of speed. I ran into a curious issue with my Corsair M95 where it would randomly stop responding (lights would go off and back on in about half a second), and when it was responding the button assignments I had setup in the mouse software outputted seemingly random characters (set up a button to hit 1, wou. Low speed and high speed USB devices and Compatibility Also referenced as the SuperSpeed Micro USB B connector, this connector stacks five more pins on the side of the USB 2.0 Micro B connector to achieve the full. But slow speed still remained a hindrance and a trouble. But gradually, the popularity of easy plugging devices and the USB port increased and more devices like digital cameras and camcorders began to switch to USB cable for transferring data by connecting to computer. These devices transmitted only a small amount of data to function. Back to basics here - we need to look at how I/O actually works. Examples of initial USB are – keyboard, mouse, game controllers etc. Linux CENTOS 7 / various Windows OSes and servers New 11. The initial version of USB did not support high speed data transmission since it was intended for slower devices. Note that since there are other factors that affect the total throughput, the true speed or the real world speed of both specifications is lower than the specified theoretical maximum. The maximum speed that USB 1.0 devices can achieve is 12Mbps while 2.0 devices can theoretically achieve up to 40 times of that at 480Mbps. USB 2.0 and USB 1.0 differ in the data transfer rate they are capable of.
