HP Pavilion usb not work with Windows 7

I have HP Pavilion dv9910us. I updated from Vista to Windows 7 Ultimate 32 as soon as it was released.

 

It worked fine until a couple of weeks ago. My two usb drives on the left side quit working. When I plug something into them their power light comes on, but they do not show up on the computer. I tried uninstalling the USB Root Hub but that did not help. Today one of the USB ports on the right side started doing the same thing. That just leaves one USB port working.

 

I am thinking about going back to Vista and see if they work, but I don't want to unless there is no other way.

 

Does anyone have any solutions.

Re: HP Pavilion usb not work with Windows 7

Have you checked Disk Management to see if you can assign a drive letter to the USB drive?

    I used Device Manager to uninstall the usb ports but, I don't know how to assign a letter to the port.

    First, re-install the USB, then right-click My Computer, go to Manage, and then go to Disk Management, plug in the USB and see if it shows up there.

    No it does not show up in the disk manager. It seems odd to me that three of the usb ports quit working. (not all at once but days apart)

     

    It makes me think it is a software problem and not a hardware failure. That's the reason I was thinking about restoring Vista and see it it works. But, I hate to have to reinstall all of my programs and settings.

    Well if you have a USB device like a bootable USB or USB keyboard you could plug it in and see if the system recognizes it prior to Windows loading.  For the Bootable USB try pressing F9 at bootup to get to the boot options screen and see if the USB device is listed, then proceed to test the other ports in the same manner.  For the keyboard just press F9 or F10 to see if it will register the command and again test the other ports in the same fashion.  If the test is successful then you know the issue lies within the software.

    Re: HP Pavilion usb not work with Windows 7

    I am not using a bootable usb device. I am using my iPhone and my wireless mouse. The computer plays a sound when they are recognized. Only one of the four usb ports plays the sound and recognizes them when I plug them in.

     

    Thanks for trying to help.

    Does your Wireless USB mouse work in the BIOS?  You could try testing it that way.  We don't want Windows to test it because we know the result.  The BIOS is independent of Windows and will give us a second opinion so to speak.

    I don't know how to test it in the BIOS.

     

    I did boot up with UBUNTU. Just the one usb port worked.

     

    I guess it is a hardware issue.

    That is also a good way to determine the issue.  So you have it narrowed down to the system board.  In the meantime you could always pick up a cheap USB Hub that would give you more ports.  Or ask Santa for one.  Happy Holidays.
