The USB Ports have stopped working. when I plug in a thumb drive or mouse in any of the four ports the computer doesnot respond.
the memory stick flashes once and only once when it is inserted. The laser mouse lights up but doesn't work. Can you help?
Device manager showes the USB ports and USB hubs present and no conflicts.
Both my usb ports stopped working. I thought it was just the mouse,but the printer ,and webcam dont work. When I try to use the webcam,i get the message "webcam not found" although the light on the camera comes on. The led in the mouse doesnt come on. Device manager shows everything OK. Whassup?
I think you might have a loose cononection for the data ports. Try putting a little bit of force on the usb device. Up, down left right. NOT ALOT. If it starts working when force is used, i tihnk you should try to take it apart and resolder the connections. If it dosen't work, uninstalling the driver and installing.

Well, to get started I would need to know what operating system your using. For all of your USB ports to stop working, Something has corrupted your device manager or has re-configured your startup. If your using Windows, start in safe mode and try system re-store to a date when the system was stable.
Do you have another USB mouse around that you can test with? It sounds like the USB port on your laptop is fine but the mouse is the issue.
If you can find a spare around and test or alternatively you could try to bring the laptop to a friends house and borrow their USB mouse temporarily.
My guess is that the other mouse will work fine. How many USB ports does this computer have? You can also try changing which port you plug it in to.
Well let me be the first to say I see you have skills. All of your troubleshooting is exactly by the book. The only thing I see that was not checked is the CMOS (BIOS) setup screen to make sure that the USB function is enabled there. Good luck and let me know how it goes, we have a couple of hundred years of experience at FixYa so keep me updated if you have any more problems.
I fixed the problem by going to "Device Manager," then to the "Universal Bus". Under "Universal Bus" are a list of the individual USB ports. You have to delete each one individually. When you delete each one, a window opens up which gives you various headers; select "drivers" and hit "uninstall". When you hit "uninstall", windows will ask if you want to proceed. Select "Yes". You'll then get a "warning" that the computer may not work correctly if do this procedure. You want to proceed with the deletion of each Universal Bus port. Once you've removed the Universal Bus ports, then reboot windows. Windows will detect the individual Bus ports and find new drivers for them. Once the drivers are installed (automatically by Windows), the USB ports will be operational.
I think the root issue of usb ports not working is a problem with your USB port's drivers no longer communicating with your computer. This often occurs when you install an update to your computer's operating system.
One of the great features of USB devices is they can get power from the USB port. Plug in a thumb drive and it just works. The power for operating the thumb drive comes from the USB port. This works for small devices like a thumb drive but not something big like a scanner. The scanner need its own power supply.
There could be several explinations for what you are seeing. Could be you are plugging in a device which is sucking too much power and the laptop is shutting it down. I would test the port with something small like a thumb drive and see if it works. If the thumb drive works but the other device does not a couple of things could be going on. Maybe the device just need power - is there a way to plug in a power supply? Or maybe the device is broken and shorted out. Does the device work on another computer?
If something like a thumb drive does not work then it is a problem with the motherboard. Could be the USB ports are bad. It happens and there usually is no easy fix short or replacing the motherboard ($$$). Occasionally there is a BIOS setting for the USB ports. A bit of a long shot but worth a look.
A possible work around would be to get a power USB hub. A hub plugs into a USB port and provides 4 or 7 USB ports. Good ones come with a power supply. When the hub is plugged into the power supply it does not draw power from the computer. Might solve your problem.
Device manager shows the USB port if they are attached to you notebook. And in your case they are attached.
So it will show it.
Now in your case the problem is in your USB.
Get it changed. If it is in warranty peroid then dont u take any risk. Let it be replaced. Or give your notebook in warranty period to the company from which you bought.
