A very important way to connect two PC is to use a USB-USB cable. By connecting two PC with a cable like this, you can transfer files from one PC to another, and even build a small network and share your Internet connection with a second PC. In this tutorial, I will elaborate you how to connect two PC using this type of cable.

Firstly, I should be aware of is that there are several different kinds of USB-USB cable on the market. The one used to connect two PC is called “bridged”, because it has a small electronic circuit in the middle allowing the two PC to talk to each other. There are called A/A USB cable that, in spite of having two standard USB connectors at each end, don’t have a bridge chip and cannot be used to connect two PC. In fact, if you use an A/A USB cable, you can burn the USB ports of your computers or even their poIr supplies. So, these A/A USB cable are completely use-less. A/B USB cables are used to connect your computer to peripherals such as printers and scanners, so they also would not meet your needs.

As for speed, the bridge chip can be USB 1.1/USB 2.0. Obviously, the study shows that that you buy a USB 2.0 bridged cable because of its very high speed. Just remember, the standard Ethernet network works at 100 MPs’, so the USB 2.0 cable will provide a transfer rate almost five times higher than a standard network connection.

To analyze the USB wire open the bridge located on the middle of our cable to show you that this kind of cable really has a bridge chip, and that’s why it is more expensive than a simple A/A USB cable that doesn’t have any circuit at all.


There are a total of 4 wires

  • Red
  • White
  • Green
  • Black

A silver coat shielding them, and a steel wire which covers all of them. The sensor bar cable has 2 wires, which are red and yellow. Connected the red wire to the red one of the USB cable. The problem is that no matter which wire of the USB cable I connected the sensor bar yellow wire to, it always worked. If you know a thing or two, please explain why all wires worked.
