ONE OF MY 2 USB PORTS ON MY DELL LATITUDE D6OO DOES NOT WORK. I TRIED THE FOLLOWING FIX, >START>RUN>DEVMGMT.MSC AND THEN UNINSTALLED ALL USB CONTROLLERS, RESTARTED MY LAPTOP (WITH WINDOWS XP PRO) TO REINSTALL THEM, WHICH IT DID. THE USB PORT STILL DOES NOT WORK. CAN YOU RECOMMEND ANOTHER FIX OR IS THIS A HARDWARE PROBLEM? THANKS, ROGER.

Both USB ports use the same driver, so if one works and one doesn't, you have a mechanically bad port. You'll need to replace the hardware to solve the problem. There are usually a lot of bad D600 motherboards on Ebay. Or try to find just the USB port you need. Fairly simple replacement task, but laptop dis-assembly will be required to reach the part.

SOURCE: ONE OF MY 2 USB PORTS DOES NOT WORK ON MY DELL

Hi Roger,

The Windows command you used to uninstall the USB port is correct. If they all work bar one, then i think its safe to say it's possibly a hardware issue.

The only other fix i can think of is to update the BIOS with the latest version from the Dell support website.



Good luck.

Hi,

Here are some steps which you can try. It is not always that the device is defective. Maybe the generic USB controller/driver needs to be uninstalled then reinstalled or the USB port itself is broken.

- Go to Device Manager -> Right click USB Controller -> select Scan for Hardware Changes.
To go to the Device Manager in xp (Start -> Run -> type devmgmt.msc -> press Enter or OK), in Vista and Windows 7 ( Start -> type devmgmt.msc on the start search box -> press Enter)

- Access BIOS setup (either Del, F2, F10...depending on the laptop brand) then look for the option to restore default BIOS settings.

- Go to the Device Manager and unistall everything under the USB Controller then restart the unit. It should automatically reinstall the driver. Try to use multiple USB devices if possible.

- If the above steps will not work, you're USB port may be defective already.

I hope this helps. Please reply if one or any of these steps resolved your issue for the benefit of other users having the same problem as yours.

Regards.

Hi!

What you could do is first check in the device manager. Go to control panel and click on system. From there on the top click on hardware. Then click on device manager. Look for any icons that would have an X, ?, or ! on it. If they do right click then click update.

If that still does not work go this page

and download all the drivers including the chipset and reinstall them.

I hope this helps.

Check your Device Manager "Start > Run > devmgmt.msc" you may have not installed controllers for your motherboard. Look for "!" and install the drivers using your motherboard driver disk. If driver CD is not available you can download updated drivers from Gigabyte Support Site.

USB ports not working


Method 1: Use Device Manager to scan for hardware changes loadTOCNode(2, 'resolution'); Use Device Manager to scan for hardware changes. After your computer scans for hardware changes, it might recognize the USB device that is connected to the USB port so that you can use the device.

To scan for hardware changes, follow these steps:
  1. Click Start, and then click Run.

    Note If you are running Windows Vista, click Start, and then use the Start Search box.
  2. Type devmgmt.msc, and then click OK. Device Manager opens.
  3. In Device Manager, click your computer so that it is highlighted.
  4. Click Action, and then click Scan for hardware changes.
  5. Check the USB device to see whether it is working.
If scanning for hardware changes fixed the problem, you are finished. If this method did not fix the problem, go to Method 2.
Method 2: Restart the computer loadTOCNode(2, 'resolution'); If scanning for new hardware did not fix the problem, try restarting the computer. After the computer has restarted, check the USB device to see whether it is working.

If restarting the computer fixed the problem, you are finished. If this method did not fix the problem, go to Method 3.
Method 3: Disable and re-enable the USB controller loadTOCNode(2, 'resolution'); Use Device Manager to disable and re-enable all the USB controllers. This lets the controllers recover the USB port from its unresponsive condition. The USB controllers represent the USB ports in Device Manager.

To disable and re-enable the USB controllers, follow these steps:
  1. Click Start, and then click Run.

    Note If you are running Windows Vista, click Start, and then use the Start Search box.
  2. Type devmgmt.msc, and then click OK. Device Manager opens.
  3. Expand Universal Serial Bus controllers.

    Note You might have to scroll down the list to find this item.
  4. Right-click the first USB controller under Universal Serial Bus controllers, and then click Uninstall to remove it.
  5. Repeat step 4 for each USB controller that is listed under Universal Serial Bus controllers.
  6. Restart the computer. After the computer starts, Windows will automatically scan for hardware changes and reinstall all the USB controllers that you uninstalled.
  7. Check the USB device to see whether it is working.

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.

hmmm..

Start > Run > devmgmt.msc

Check if there are some errors shown under USB devices..

Also try changing the USB ports...

Use the ports in back of ur CPU.

Also check

Start > run > diskmgmt.msc to see if your device / Hard disk is listed there.

Assign a drive letter to the drive if no letter like e:, f: etc is assigned to it.
