by Rohit Khurana on December 28, 2012


One of the most commonly faced problems by many Windows users is problem faced when using a new USB device which they have never used before on their computer. Such devices can be anything which uses USB like a USB pen drive, USB Web-cam, printer, mouse, keyboard, scanner, bar-code reader etc. It is usually quite frustrating when the USB device you bought does not work, the first thing which comes to the users mind is that the device is faulty, which maybe the case sometimes, but most of the times, its otherwise. In this article, I share some general tips on what to do when your new USB device does not work or is not detected by your computer. Read on for more details.

USB Device Not Detected on my Computer

Not All Devices Are Plug-And-Play

While many normal USB devices like USB mouse and pen drives etc. are plug and play, not all of them are. Which means many devices require you to install driver softwares (usually supplied with devices) to use them with your Windows computer. So check the box of the device for a quick-start guide on how to install the drivers, after you install the drivers, restart the computer and plug-out and plug-in the USB device again. This will solve the problem for most of the users.

Also many devices like printers, cameras etc. have power on button. They are detected only when they are in power on mode.


Not All USB Ports Are Good

You might laugh at me, but in my years of experience with the computers, I have seen many USB posts on the old computers going faulty, especially the ones which are at front of the desktop cases are highly prone to fault. Also if you are using USB hubs or extension cables, they might be interfering with the device communication with the computer. Try switching to some other USB port on the computer and your device may start working, has happened with me many times.

Check Device Manager

Go to Control Panel > Device Manager and check the section “Universal Serial Bus Controllers”.  Plug out and plug in the device and see if there is any change in this section when you plug in the device. If not, then probably the USB port is not reading the device at all.
