On both the compaq laptops owned by my daughters, one or more USB ports have gone dead. The fix has required dissassembly of the unit and really careful resoldering of the pins from the USB ports to the motherboard. It apparently takes very little torque on the USB connector to break the solder joints and as my daughters tend to use their laptops in a manners that stress the connectors ( on the couch or bed for example) the internal connectors just plain break. Cheap *****if you ask me.

Reinstall your USB drivers:
Navigate to Device manager, find a branch named "USB Controllers" or similar
Right click the one thats the problem (or all of them if you dont know which), select Uninstall
Reboot your machine and windows will autodetect the USBs and reinstall their drivers.

    Disable power management on the USB hub
    To preserve power, Microsoft Window XP tries to disable USB when a device is not used. Under certain circumstances this function does not work and may cause USB devices to fail to respond when called. To resolve this issue, disable power management on the USB hub by doing the following:

    1. Click Start , and right-click My Computer .

    2. Click Properties , then click Hardware .

    3. Click Device Manager .

    4. Double-click the Universal Serial Bus Controllers branch to expand it.

    5. Right-click USB Root Hub , and then click Properties .

    6. Click Power Management .

    7. Deselect Allow the computer to turn off this device to save power .

    8. Repeat Steps 5 through 7 for each USB Root Hub.

    9. Click OK , and close Device Manager .

I have an Acer Aspire 5253/BZ815 that is only 7 months old. 2 of 3 USB ports don't work, webcam stopped working and sound is going out. How do I get these things fixed?

From your description the motherboard is failing or windows device drivers are corrupted, if it is the device drivers you can attempt a system recovery from the hard drive or DVD disc which will reset everything back to factory default with a fresh install of windows. But if you find there is no change your manual should list aurthorized service centre's closest to you, or go online for customer and technical support.

My USB Ports don't work. Is this just a plug and play to replace or do I need to purchase a new CPU.

is it only one or all usb ports that doesn't work. Check your device manager and see if the Usb device are still working or the computer is able to detect it. If it is, and is able to detect and display your Usb ports then they should be working alright. There has been a virus that been going on lately that cause the computer not to read device detected to the usb ports since I had this same promblem before and it wasn't a hardware issue, but a viral issue. Had to run the latest definition and then formated my laptop to factory default.

Power light comes on but no accessories will work when plugged into USB ports

1.Plug in a different USB device in that USB port and check if it is working or not. If the 2nd device is working then the 1st USB device has gone bad. If none is working then try the steps mentioned below.
2.Unplug the powercable from the laptop and also unplug the battery. Press and hold the power button for 30-40 secs and then plug in the power cable and the battery and check. on START->right click on COMPUTER->click on MANAGE->click on DEVICE MANAGER->click on the symbol beside Universal Serial Bus Controller and uninstall all the USB ROOT HUB's and then restart the computer.
4.Run System Recovery from the Recovery Partion or Using the Recovery Disk.

Still if it remains then it is surely a hardware issue

HP Compaq Presario V6030 usb ports don't work, is this something I can fix with drivers or can they be replaced.

First try these steps
1.Remove all the usb devices connected, then go to device manager and under Universal Serial Bus controlers uninstall all the usb root hub and then restart the computer
2. If it still doesnt work do a bios update from for your notebook and then restart and do a bios default too.
3. If these steps doesnt resolve the problem do a recovery and even after recovery the NBs usb ports doesnt work then mother board needs to be replaced as the usb ports are fixed in it.

The usb port won't work on my acer extensa 4630z laptop

Did you install any Anti virus . Check the USB port for any physical damage. Try connecting a mouse with USB port to check if its working. After all this then the issue remain the same then the USB port needs an replacement.

All usb ports stoped working

.There are a lot of virus' that will disable your USB ports. You can change the settings in the registry to enable them again.

Open registry (START > RUN> type regedit) and navigate to the following registry key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet \Services\UsbStor

Now in the right pane, double-click Start and type 3 in the Value data box (Hexadecimal) and quite the registry editor.

USB ports not working Acer Aspire laptop

Two solutions would be to either restore your pc to before the problem started,using system restore on accesories menu, or use the recovery cd or the recovery folder Acer laptops usually have on the 'D' drive and re-install usb controllers and drivers.
