What’s USB?

USB, short for Universal Serial Bus, was invented to standardize the connection of many peripherals: keyboards, pointing devices, digital cameras, printers, portable media players, disk drives and network adapters.

Almost everyone now has two types of USB:

  1. USB 2.0
  2. USB 3.0

USB type 3.0 provides better speed and more efficient power management than USB 2.0. However, sometimes you can’t differentiate between those two versions of USB. Here’s a couple of hints to know whether your USB is 2.0 or 3.0:

Check the logo

Since USB 3.0 is also knows as SuperSpeed USB, you can easily find the SS mark around your USB port.

Check the color

Most of the time but not always, the USB 3.0 port should have blue color inside the port (even if it doesn’t have the SS mark) whereas USB 2.0 has either black or white inside the port.

USB device not recognized

Sometimes when you plug in a USB device, an error message appear saying that:

USB device not recognized, the last USB device you connected to this computer malfunctioned, and Windows does not recognize it.

As the message says, the USB can be damaged or Windows may not be recognizing it. So, let’s begin our solution to this problem.

I- First of all, make sure it’s not a hardware issue

Try your USB device on another computer, if the same message appears then it’s more likely that your USB device is corrupted or damaged, that’s why it’s unable to function.

II- Remove all other USB devices and USB hubs
