با هر کابل usb نمیشه اینکارو کرد. چون اصل کار اون قطعه سخت افزاریه که وسط کابل هست و نرم افزاری که همراش فروخته میشه. قیمتش هم حدود 10 هزار تومنه.

Connecting Two PCs Using a USB-USB Cable | Hardware Secrets
Introduction A very easy way to connect two PCs is using a USB-USB cable. Connecting two PCs 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 we will explain you how to connect two PCs using a cable like this.
The first thing you should be aware of is that there are several different kinds of USB-USB cables on the market. The one used to connect two PCs is called “bridged” (or “USB networking cable”), because it has a small electronic circuit in the middle allowing the two PCs to talk to each other. There are the so-called A/A USB cables 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 PCs. In fact, if you use an A/A USB cable you can burn the USB ports of your computers or even their power supplies. So, these A/A USB cables are completely useless. A/B USB cables are used to connect your computer to peripherals such as printers and scanners, so they also won’t fit your needs.

As for speed, the bridge chip can be USB 1.1 (12 Mbps) or USB 2.0 (480 Mbps). Of course we suggest you to buy a USB 2.0 bridged cable, because of its very high-speed. Just to remember, the standard Ethernet network works at 100 Mps, so the USB 2.0 cable will provide you a transfer rate almost five times higher than a standard network connection.
We decided to open the bridge located on the middle of our cable just 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.

Now that you know the kind of cable that you should buy (on the top of this page we are listing several places you can buy this cable online), let’s talk about its installation.
