USB devices keeps on disconnecting

Asked By 200 points N/A Posted on -

For some reason I always getting a message that says my usb device is disconnected. After a couple of minutes, it will say connected again. It’s very annoying to hear the disconnection sound.

Right now these are the usb devices that are connected to my Dell Optiplex.

  • USB optical mouse
  • USB stick modem
  • Keyboard

I don’t know if the problem is on my devices or with the usb port of my computer. I tried unplugging them all and use them one by one but I still got that message. Also, I checked device manager and everything seems to be fine.

Dear Susan Martin

  • you need to setup your USB device again. To do this open the CPU box and see the motherboard manual. there you will find the diagram where the USB ports are connected. There check according to your diagram. you open them up , and reset them there.
  • Again in the windows in device manager, disable all the USB panels and install them again .
  • This will solve your issue.

Thank you for your query.

  • The possible cause of this problem is power fluctuations. Your USB devices may not be receiving adequate power need for it to function normally.
  • To fix this, try to disable all the power saving options in your computer. You can do this by going to "Control Panel", click on "Power Options", and choose a different power scheme.
  • Another possible reason is that your USB slot has loosened. You can buy a new USB hub, connect this one to your "good' USB port and try connecting all your USB devices into this hub.
  • Or, you can also opt to change your USB slot.

Hope this helps.

USB devices keeps on disconnecting


I also use USB mouse and keyboard but I don’t see any message on the system tray to prompt me whenever the device gets disconnected or reconnected. I only usually see a notification when a new device is plugged in or when there is a problem with the device the time I plug it on the USB port.

Usually, when this happens, I just unplug the USB device from the USB port and plug it back in. In your case, just try plugging the USB device to another USB port. If you are using a desktop computer, you should have four (4) USB ports at the back of the CPU and one (1) or two (2) more USB ports in the front.

Try connecting your USB device to all those ports to troubleshoot. If this doesn’t work, try updating the drivers on your computer. For Dell computers, head down to Dell Drivers & Downloads. Here, enter your computer’s service tag or model number then click to search. When your product is located, click it to go to the download page.

On the next page, go to the drivers download section or tab. Your operating system should be detected automatically. If a different operating system is displayed, click to change then select your correct operating system. Download and install all available drivers and software for your computer.
