I have a Craig mp4 .. but I'm trying to use it but i do not how .. because when i connect it to the computer it is not recognized by the computer please help me


Hi, Are you getting a "USB device not recognized" error whenever you plug in a USB mouse, keyboard, or other USB device? I love USB and have 5 ports on my computer so that I can connect my mouse, keyboard, camera, phone, and printer to it all at once!

However, last weekend, my computer stopped recognizing my USB devices! The strange thing about it was that the USB ports were not bad because all of my devices were still getting power to them. I could still charge my cell phone without a problem!

usb device not recognized

So I started with the normal fixing methods, including uninstalling the drivers for my devices and reinstalling them. That didn't work! Next I tried System Restore thinking that maybe I had installed something and it caused a conflict with the USB system drivers. That didn't work!

I read online that in order to fix this problem I should go to Device Manager and uninstall all of the devices under USB Controllers. Restarted the computer, reinstalled the USB drivers, but the problem STILL did not go away!

You may also see in Device Manager that the device shows up as an "Unknown Device".

unknown usb device

So how did I finally fix the problem? Well, apparently it's a super simple solution! No need to edit the registry, uninstall drivers, or anything of that sort.

Simply UNPLUG YOUR COMPUTER FROM THE POWER SUPPLY. Yes that's it! Note that this does not mean just turning off your computer because modern computers don't really turn off when you press the power button as the motherboard still gets power.

First to explain, the motherboard is where all of hardware of the computer is connected to, including the USB ports. Sometimes the motherboard needs to be "rebooted" also because something can go wrong, i.e. all your USB ports suddenly stop working. The small microprocessor on the motherboard will reload the drivers and your USB ports should be back to recognizing all devices!

So first turn off your computer using Shut Down or pressing the power button and then UNPLUG it from the wall outlet. Let it sit for about a minute and then plug it back in.

Hope this helps someone fix that pesky "USB device not recognized" Windows error!


Have a nice day...

One of my usb ports won't work properly. If you plug something to it for longer than half an hour the usb port stops recognizing the device you plugged. I have an hp dv7 4190us laptop.

I have a WD passport 320gb, at first it worked one of my usb. then all of sudden, it stop recognizing my WD Passport with one usd port, so i plug it in another usb then it works. and after a couple of days...


Are you using an external power supply for the disk? If not, you might be overloading the USB port. It should not happen, but USB ports are limited in the amount of power they can output. Especially laptops might face such problems.

Do other USB devices still work on those USB ports? If so then the port is at least not broken.
Sometimes you can uninstall and reinstall the USB hubs and controller devices in the Device Manager to fix USB problems.

I added a 512mb stick to my ibm t30 think pad and one port is bad


You can plug a USB hub into the working USB port on the computer. The USB hub can have several ports so you can plug in several USB devices.
I suggest you get a powered USB hub because if all the devices that you plug into this hub exceeds 500mA then your computer's USB port will stop working because it could not supply enough current.
You will not need to plug in the power adapter into the hub if the device/s do not overload the computer's USB port.

Usb ports


  • The driver for the device is faulty. When you plug in a USB device, the computer should load and then configure the device without ever requesting a device driver. If the computer prompts you for a device driver, check the information that came with the device or go to the manufacturer's website to see if a driver is available.
  • The USB port might be defective. If the USB device is connected to a defective port, the device will not work. Try plugging the device into a different port. If all the USB ports are being used, unplug a device that you know works, and then plug the problem device into the port that device was using.
    If the device is plugged into a secondary USB hub with other USB devices, unplug the device from the hub, and then plug the device directly into a port on your computer.
  • Other USB devices might be drawing too much power from the hub. The device you are trying to use might require all the available power or bandwidth that your computer can provide. If other USB devices are connected to the computer and are drawing power from it, the first device might not work. If any other devices are drawing power from the hub, try disconnecting them, and then see if your device works. If this solves the problem, you might want to obtain a USB hub with its own power supply so that you have adequate power for all devices.

    Usb ports


    You'll want to verify your computer recognizes your usb ports.
    In device manager, look to see that you don't have anything with an exclamation mark, question mark, or red X on it. Make sure you have the usb ports listed under Universal Serial Bus controllers. If nothing shows, your usb ports may be dead. Depends on the age of your computer and what might have happened to them.

    Device manager- right-click My Computer and go to properties, then select the hardware tab.
