Check your settings in your BIOS for the USB ports.

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

USB not working


If none of your USB ports work, there could be a problem with your USB controllers. Uninstall the USB controllers via Control Panel - System ... and reboot your laptop. They will reinstall upon bootup. Good luck.

USB PORTS


does your usb mem stick have any light indicators? if yes , whenever you put you usb stick, does it light? if it lights are USB ports is still ok,  You just have to reformat or partition you USB stick.
(you can also try other devices like usb mouse or any usb devices that lights up when you connect it)

if there are no lights if you plug, or no indication that a power goes to your stick, its possible that your usb your are busted. if this is the case, if your laptop has a PCMIA slot, you can find a pcmia USB card, if you dont have. your only option is replace the  motherboard.

USB Ports Not Working


Check Device Manager for bad drivers

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....

USB Ports


I would go back to device manager and uninstall all drivers in the USB category. Reboot and Windows will re-detect all the USB ports, this should work. If it was an electronic problem then some ports would work and other wouldn't but not all since there is multiple USB controllers in most computers these days.
