My dell latitude d600 usb ports stopped working how can i get it fixed. thans


If ALL the usb ports have stopped working, this is a problem with the USB controller. The short answer is that you cannot easily repair this. In all probability, the controller, or a circuit trace to it has blown or shorted. You would need to get another motherboard.

If one is still working, then you can get a PCIMCIA card to usb port that will give you 2-4 extra ports, but this will only work if at east one of your existing usb ports is still functioning

In my laptop USB PORT is not working


USB driver needs to be re-installed. Go to: 1. My Computer 2. Right click and choose 'Properties', 'Hardware', 'Device manager'. 3. Find and click on 'Generic USB Hub' and click 'Uninstall'. 4. Restart your computer.
After it reboots, it will find the hardware and automatically reinstall the correct driver.
This should restore USB functionality.

ONE OF MY USB PORTS STOPPED WORKING ON MY DELL LATITUDE D600 PC NOTEBOOK.


A shot in the dark here, but try this: Click Start>Run, type devmgmt.msc and press enter. Click the plus sign beside "Universal Serial Bus Controllers." Right click each listing that appears underneath "Universal Serial Bus Controllers" and click Uninstall. Click OK on the confirmation dialogs. After you get done uninstalling all of them, restart your computer and Windows should reinstall them. After it is done, try that USB port again.

Gateway USB ports stopped working


So maybe you need to install the drivers for the USB device you are trying to connect. Also, with the computer off, try cleaning all USB ports and plugs. You can buy electrical cleaner in a spray can at Radio Shack. Let it dry thoroughly before powering up. But to me it sounds like a driver problem. Unless maybe your USB BUS is going bad.

USB


First of all, I recommend you to Uninstall the USB Devices from the Device Manager and reinstall the Chipset Drivers as per the instructions below :
Click on Start and then on Run.
Type devmgmt.msc in the Run Command box and click on OK.
This will open the Device Manager window.
In this, click on the + mark next to Universal Serial Bus Controllers which will display additional USB Entries.
Right click on each of the entry and select Uninstall.
Click on OK if you get any confirmation window. Repeate the same process untill there are no entries left under Universal Serial Bus Controllers in the Device Manager window.
We are done with uninstalling the USB Drivers from the Notebook.

Now, restart the Notebook and close any window which says 'Found new hardware'

Now, download and install the Chipset Driver in your Notebook from the link below :
http://downloadmirror.intel.com/8178/a08/infinst_autol.exe

Save the file in the Notebook and double click to install the Chipset Drivers.
However, if the issue with the USB Ports persists, I recommend you to check again with different devices to confirm if the issue is with the USB Ports of the Notebook itself.
If the Notebook doesnot recognize any of the USB Devices after installing the Chipset Drivers, you may need to get the USB Ports of the Notebook replaced or go with a PCMCIA USB Card.
Hope this helps....
