Question about HP Pavilion dv8000z Notebook

1 Answer

I have same problem. My usb ports just quit one day.

I have restalled BIOS, removed USB ports and scanned for new hardware on device manager, turned off power management, etc., etc. - nothing has worked.

Any other suggestions? Also, do you know anything about wireless keyboards with USB ports - do you have to have functioning USB port on laptop to plug into?

Thanks.

    Micromend, I tried your solution, but it didn't work.. Thanks anyway.

    However, I did find a fix for my problem. I bought a USB 2.0 PCMCI card and inserted into PC card slot and now I have two working USB ports.

Hello

Your problem was cut off but I'm assuming it's that you've lost your USB ports. If this is the case then either you have a virus interfering or a Windows file is corrupt. First run these AVGFREE, MALWARE BYTES and SUPERANTISPYWARE. Once you've insure the machine is clean then goto Start, Run and type SFC/scannow. This will put all the Windows files back where they belong. You will need your original Windows disk.

Hi, I try to plug my MP3 into one of my USB ports. Doesn't recognize it. 'Removable Disk (H:)' comes up in 'My Computer', but soon disappears.


There is a problem with your USB port
you should try getting them fixed which is a tough job, but you can try plugging your removable media into another USB port like USB ports in backside of the cabinet.
If you don't find any problem with your USB device then you must have been having problem with your Removable Media (Mp3)
If your MP3 Player is under warranty period then you can look for its repair (can be done if its out of warranty too, but it will charge you extra)
Solutions To work around the above issues, one of the below solutions could prove helpful:usb-device-not-recognized.jpg
  • Unsecure or Loose Connection
    Unplug the presently connected USB device (if any). It is quite possible that the connection is not secure and has become loose. Re-plug the USB device tightly and firmly into the USB port. This is one of the most common reasons for an error in detecting a USB device.
  • Scan for Hardware Changes in Device Manager
    Use the Device Manager to scan for new and recently installed hardware. From the Start menu, select the Run option. In the pop up box, type in Devmgmt.msc and then click Ok. From the Action menu, click Scan for hardware changes. This will make Windows scan & recognize any new devices that are installed. Now, close all opened device managers and control panels. Now, follow the above step and see if your computer detects the USB device.
  • USB Power Management
    Disable power management of the USB hub. To disable the power management on the USB hub, follow these steps; Click Start, and then click Run. Type devmgmt.msc in the popup box, and then click Ok. Expand the Universal Serial Bus Controllers' node, and then follow these steps for each USB Root Hub that is listed. 1. Right-click the USB Root Hub and then click Properties.
    2. Click the Power Management tab.
    3. Click to clear the Allow the computer to turn off this device to save power check box, and then click Ok.
    Note: If you perform the following procedure on a laptop computer, you may reduce the battery life.
Sometimes, simply unplugging the USB device and turning off the computer for twenty minutes and then restarting may solve the issue. If none of the above options have solved the problem, check the manufacturer's website for new driver information. It is possible that your drivers need to be updated. There could also be a possibility of hardware failure, which needs to be checked by a hardware expert

My pc window can not recognize mp3 player


Hello

Connect your Sansa MP3 player to more than one USB port on your computer. Ensure that your computer USB port is not corrupt or disabled by testing at least two available ports. This is especially useful when you possess no other USB-based equipment.

Inspect your USB ports' status to ensure they are enabled on your computer. Right-click "My Computer" and launch "Properties" to verify the availability of such connections. Select "Device Manager" from the Hardware tab and click the "Universal Serial Bus Controllers" from the list shown. If a red "X" is shown, the USB ports are disabled.

Ensure your computer is updated by clicking "Start" and launching "Windows Update" from the Programs menu. Alternatively, inspect your USB port connectivity through your motherboard BIOS settings. Note that BIOS access and settings varies by mother board manufacturer.

Scan your computer for new hardware changes. From the Device manager, click the "Action" menu and select "Scan for hardware changes" while your Sansa MP3 player is connected. Allow your computer to attempt to find any physical component recently added in the event it failed to previously detect it.

Connect your Sansa player to a different computer. Test the connection on a different system's USB port to verify that the Sansa device's own connection has not been damaged. Inspect the USB ports on the computer in question as well to eliminate the possibility of both systems having problematic USB ports.

Change your Sansa MP3 player's USB plug. Sometimes the head of the plug may lose contact with the appropriate circuits. Obtain a secondary USB port at your local retail store and test it on an updated computer system.

Problem with usb port don`t work


Step 1
Before you start working on the USB port, make sure that your device is not the problem. If the computer says that the there is a new USB device but that it cannot use it, typically there is a problem with the device's driver and not the USB port. If this is the case, your best option is to re-install or upgrade the device driver. Try inserting the device to another computer. If the device works, most likely the problem is with the computer and not your device.

Step 2
Try rebooting the machine. Rebooting a computer resets all of the software to the default state and will clean up many issues. The start up process also checks all of the devices on the computer and can sometimes fix a USB port. First shut down the machine. Connect the USB device up to the computer and start it. This reboot will sometimes fix a bad USB port.

Step 3
Try attaching the USB device on to another USB port on the same computer. If the device now works, the old USB port probably has a hardware or BIOS issue. Skip to step 5 to try to fix a bad USB port through the BIOS. Fixing a hardware problem on a USB port requires working on the motherboard which is typically more expensive just adding a new USB ports.

Step 4
Uninstall your computer's USB device bus manager. The device manager controls the USB access and sometimes gets corrupted. Fixing the USB device manager requires administrator rights on the machine. The best way to uninstall the device bus manager is to right click on your computer's icon and select properties. This will bring up the hardware settings for your machine. Click on the hardware tab and select the device manager. The device manager lists all of the devices on the computer. The next step is to open up the "Universal bus controller" option. Right click on all of the items under this option and uninstall them. Once all of the devices have been removed, restart the machine with the USB device connected. Upon reboot, windows re-installs the USB device manager. Most of the time, this will fix the USB port.

Step 5
The next thing to try is to check the BIOS. Restart the machine and enter the BIOS setup screen. You should check to make sure all of the USB ports are active. If they are, you should try resetting the BIOS settings to the defaults. The BIOS reset will sometimes fix USB port. But if it does not you will have to consider upgrading the BIOS. Upgrading a computer BIOS is very dependent on the motherboard manufacturer and you will have to visit your computer manufacturer's web site for detailed instructions.

Step 6
The last trick to try to fix a USB port is to repair your OS. Sometimes the USB drivers can get corrupted and break the USB ports. You can reinstall the system files onto the computer which should fix the USB port. Your data files should not be changed in this process, but it is a good idea to do a full backup of the computer ahead of time. In windows, an OS re-install is done by loading up the windows installation CD/DVD and selecting the repair windows installation. Just follow the steps and you often have a fixed USB port at the end of the process.

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

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.
