HP Pavilion DV7 2270us: USB Ports not working on HP Pavilion DV7

I get the USB device not recognized on all USB ports on my laptop.

I am running Windows 7 (recently did a restore to clean computer) service pack 1.

I refreshed the BIOS

I tried to remove all the drivers, stop, remove the battery and restart

I tried refreshing all USB drivers

I tried to adjust the power settings to make sure that all power mode on the economy USB devices has been disabled

Still no luck. From time to time I can plug something and it will work a bit then it becomes disconnected. I think this could be a hardware problem as no intervention software worked. All advice appreciated!

Hello and thanks for the display on the HP support forum.

Thank you for the great information you have provided to us.  I agree that you did already that you are looking at a hardware problem.

It seems what's your connection and once the jury warms the connection develops and is then broken.

The next step would be to contact the helpline for repair options.

Please contact our technical support at the 800-474-6836. If you do not live in the United States / Canada region, please click the link below to get help from your region number. http://WWW8.HP.com/us/en/contact-HP/WW-phone-assist.html

  • Satellite A200-1tw psae6e - USB ports not working not

    I use windows 7 ultimate on Satellite A200-1tw (psae6e-06u030du) and my usb ports no longer works correctly.
    In fact they recognize certain usb devices, but not all (for mouse and printer example work, but my USB does not work)

    Looking at the Device Manager, everything seems OK... No problem!

    Does anyone have a solution for my problem.

    Thanks :)

    Hello

    Try resetting the USB ports. This means that you need to remove the USB ports/hubs/controllers in Device Manager.
    Then, you have to restart the laptop to get new USB ports.
    In my case it has worked.

    By the way; I recommend upgrading the chipset driver and disable the feature for each energy-saving usb port.
    This can be done in the Device Manager-> port USB-> properties-> tab to save energy

  • Equium A60 - 692 USB Ports not working not

    Hi all - new to the forum and what a good place to find info on Toshiba laptops. Anyway - after a recent storm, I lost connection to my ISP broadband - contacted the helpline who advised me to Exchange my ADSL modem to an Ethernet - made and corrected the connection problem - however - only after having it done I realize has none of my devices (printer, camera, Web Cam etc.) worked via the USB ports. I've uninstalled and reinstalled the system and drivers for devices without result. The device displays 500ma of power manager is available for each of the 3 ports but watch 0ma used. The Device Manager also shows that the USB ports are working properly. Can someone help or advise if these ports on a separate card or they are part of the motherboard. If Yes, where can I get a. Congratulations to all - Andy

    A lighting strike is not good news, if she gets hit by a kind something can go wrong. My guess is that your laptop USB ports has taken suddenly by a massive power surge that probably damaged the chips inside. It could be a Windows problem, or not the only thing I could suggest is to use a bootable Linux such as Knoppix CD and run a command called usbview with some USB devices.
    If the USB has been confirmed dead then your only option is to use an adapter CardBus USB 2.0 providing your CardBus slot is not damaged too.

  • 8.1 Windows 64 - bit 3 USB ports not working not

    I have a model computer T430s 2352CTO, running Windows 8.1, 64-bit version. Before upgrading Windows 8.0 all drivers have been updated. The USB ports 3 worked properly, in particular an external hard drive of 1 GB running. After the 8.1 update, 3 USB ports work always, but only for about 30 seconds, then the hard drive stops. The power led remains on the hard drive, but it no longer displays in windows Explorer.

    In Device Manager, I'm gone to Bus USB-> USB controllers Root Hub-> properties-> (under general it says "this device does not work correctly)-> Power Management-> unchecked the box"allow the computer to turn off this device to save energy. Unfortunately, it doesn't seem to stop the problem. Any ideas?

  • HP a6554f: Front USB Ports not working for a6554f

    Hi, I cleaned the dust from my computer yesterday for the first time because the computer kept crashing. I removed the motherboard, so I unplugged everything that was clinging to her and I also removed the hard drive then plugged everything once I had finished, (do not know if I just plugged in as it was, even if I took a video of it, but the wasen can't good quality so I had to guess a little). I also added thermal compound to the cpu.

    Anyway, everyhting seems to work except the 2 usb ports front of the case. It was working fine until I opened the case (this is why I do not open the computers, but the dust was just too). The audio ports and microphone located in the front work correctly. And the rear USB ports are working properly.

    What I've done so far is running pilot Booster and also I went to Device Manager > USB Bus controllers, then I turned off everything on the list, then allowed them again. And nothing has worked.

    I don't know much about computers so I don't want to go to the hassle of opening the case cause once again I was scared lol but could I maybe hooked up a cable in the port of fake?

    Also, is there a diagram to show where each cable goes to the a6554f model?

    As you pointed out the audio before and MIC ports are working, then it might be just the plug for the ports before USB is not properly or is in the wrong place.  Here is a page that relates to the motherboard. In the lower right corner of the image or the page layout scheme, there are two blocks header before normally taken into USB ports.  Says F_USB1 and F_USB2.  Either we must work to the front ports.  Check to make sure that the wiring box beam (which has the wires going to the front USB ports) is connected on one of them.

    Hi CindyThrelkel,

    Try the following steps to resolve the problem:

    Method 1: Run the troubleshooter of material and check what is happening.

    Open the hardware and devices Troubleshooter

    http://Windows.Microsoft.com/en-us/Windows7/open-the-hardware-and-devices-Troubleshooter

    Method 2: I suggest you perform the clean boot and check.

    How to troubleshoot a problem by performing a clean boot in Windows Vista or in Windows 7

    http://support.Microsoft.com/kb/929135

    Note: After troubleshooting, be sure to set the computer to start as usual as mentioned in step 7 in the above article.

    Method 3: You can check after uninstalling and reinstalling the USB drivers , if you are able to connect. You can disconnect all USB devices and then perform the following steps:

    a. Click Start and then click Control Panel.

    b. click System and Maintenance, click System and then click on Device Manager.

    Note: If Control Panel is in Classic view, double-click System and then click on Device Manager.

    If you are prompted for an administrator password or a confirmation, type the password, or click on allow.

    c. in the Device Manager, double-click to expand the "USB Bus controllers", right click on the controller host, click "Uninstall" and click "OK".

    Check that if at all, there is an exclamation point on the pilot, it suggests problems with the installed driver.

    d. Repeat step 2 to uninstall all items under 'USB Bus controllers'.

    Then, restart your computer and Windows 7 will automatically reinstall all USB controllers.

    If you are still having the same problem then you can check the device USB drivers updated using windows update. See the following help link:

    Updated a hardware driver that is not working properly

    http://Windows.Microsoft.com/en-us/Windows7/update-a-driver-for-hardware-that-isn ' t-work correctly

    If the edge of the question persists I'll ask allows you to check the chipset driver updates you find on the manufacturer's website. The chipset drivers normally integrate USB controller drivers as well.

    You can also check:

  • Pavilion DV7: USB Ports not working not

    The usb ports on my pavilion dv7 stopped working.  In doing research I think it has something to do with the drivers, but being not not 100% technical, I'm not entirely sure how to solve this problem.  Could you please help me solve because I use quite often the usb ports as well as to synchronize my phone etc.

    Thank you.

    Hi @laci2013 ,

    Thank you for visiting the HP Forums! A place where you can find solutions for your problems with the help of the community!

    I stumbled upon your post on the laptop and wanted to help you! I looked in your question about your HP Pavilion dv7 Notebook and issues with the USB ports on 10 newly installed Windows. Here is a link to solve the USB connections.

    I would like to uninstall all listed in the universal serial bus controllers list.

    Please note remove any and all USB devices and remove the memory card in the slot of the card reader. Disconnect all non-essential devices before you uninstall the controller Universal serial bus.

    Restart your computer, and then insert the USB device.

    You can try to use the Windows Update Troubleshooter to fix updates that do not come through Windows 10.  Please restart the laptop twice to make sure that all updates are completed!

    I hope this helps.

    Thank you.

  • Pavilion dv7-4177nr: dv7-4177nr right usb ports not working not

    So I recently bought a used dv7-4177nr, got home, and since it has been used, naturally the first thing I do is restore the system to factory conditions. I don't check the ports for a feature beforehand. Run all Windows updates, get rid of the bloatware and realized, "it would be easier with my mouse wireless." Go to plug in, and the ports on the right do not recognize. No sound of "you hooked something up" or looking for drivers or anything like that. Those on the left are working fine. Windows detects that there is no ports.

    I tried the things:

    Update the BIOS

    chipset drivers of the series AMD 8 (not completely sure that those who have the right ones, but nothing else has blown up or whatever it is)

    Remove the USB drivers from Device Manager and let Windows RE-add-the

  • How I fixed my USB ports not working not problem. Two ports left side previously does not... HP Dv7

    So I do not know what is not "where it will honestly, but put there just to try to help someone else who has struggled with this as long as I did it...» I ended up having my two USB ports on the left side (turned out to be my 3.0 ports) working again when they recognize nothing. I could use the USB 2 on right 2.0 ports, but the transfer rate was terrible.

    My answer on another question where someone had a similar problem... good luck!

    'Hi. '

    Not sure if this will help, but I had the same problem, the two ports on the left did not work on my Dv7. All this time I thought that the USB on the right were my 3.0 ports so I thought that would be nice, but it's been over a year that I initially had this problem and made a bunch of maintenance of the system meant that I would look through it again. In any case, I went to the Device Manager through the computer management tool. I know that you can go straight to the Device Manager, but just give you exactly how I did it. You can search just to start computer management.

    So I chose Device Manager in the menu on the left side and it looked like ordinary Device Manager. Went down to Universal Serial bus controllers... at this stage, I watched the action menu on the right and select more actions, opinions and you click Show hidden devices. After that I went through my USB controllers one by one as I had done many times before and checked them, tried the update of drivers, etc... Under the USB controllers Section, I noticed something like xHCI Host controller of compliance Test... I right click it and went into its details, I tried the driver updated and installed the new driver. 2 new USB controllers immediately arises: Renesas Electronics USB 3.0 Host Controller and root hub.

    Switched on a test drive from the right thumb to the left and the computer instantly recognized and installed the driver for the stick.

    And that was all... hope it helps even if this is later. "
