Know the version of USB in your system

If you want to figure out the version of USB in your system then there are two widely known ways of figuring out the USB version standard available on your PC. Well some of you might not be convinced that why should they search for this kind of stuff.So for these people only do you have ever seen a message like "this USB device can perform faster if you connect it to a Hi-Speed USB 2.0 port ..." .

This is because of the different versions of the USB,version 1.0 and version 2.0 (ver 3.0 in process) both have different data transfer rates along with some other differences.Main thing is data transfer rates which is 1.5 Mbit/s (Low-Speed) and 12 Mbit/s (Full-Speed)for USB 1.0 and 480 Mbit/s (now called Hi-Speed) for USB 2.0.

So to figure out the version of USB,One of the most commonly used way is to figure it out using the MSInfo32 exe. In order to launch this exe, follow the below mentioned steps

1. Click Start->Run
2. Type in MSInfo32.exe at the input box.
3. Browse to the USB Section and you should see two USB 2.0 Root Hub Entries, if your system includes the faster version.


Alternatively, you could figure this out using Control Panel as well.

1. Launch Device Manager using the Control Panel (Control Panel -> System-> Hardware)
2. Expand USB Section.


3. If you have an ‘Enhanced’ USB host controller listed then your system supports USB 2.0. Just one or two ‘Enhanced’ controllers means your computer system is using USB 2.0
