In fact, USB transmission distance can be resolved, USB can be extended through USB? HUB transmission distance, each additional HUB, you can extend the 5 meters, a total increase of 5 HUB, which is extended 5 times, each 5 meters, so The longest extension of 25 meters. Why is the USB demanding on the distance so strict? This is because the USB signal frequency is very high, the line in the process of transmitting the signal attenuation of the signal is very large, when the signal attenuation can not maintain the normal transmission of the signal, WINDOWS will prompt "to find unrecognized USB device" So the general distance can not be more than 5 meters!
