USB ports are not working and I can't figure out what to do!

My laptop is a HP Pavilion dv4-1225dx Entertainment Notebook. I've had it for almost three years now. It is running Windows Vista, the same it came with. The problem has only just recently started or was just discovered.
My problem is that the two USB ports in the side do nothing when something is plugged into them. The metal part of the USB devices gets hot but no lights come on the flashdrive and the camera doesn't act like it is plugged in at all. I've looked through Device Manager and it says they are working fine and the correct driver is installed already. There is also no older driver to rollback to. I've tried deleting them, disabling them, and everything that has been suggested online. I even flashed my BIOS from F.33 to F.55, whatever that means, and still nothing.
Does anyone know how to fix this problem? I am a filmmaker and desperatley need my USB ports. Any help would be appreciated greatly

USB ports must be enabled in order for them to work. If you disabled them it is possible that they still are disabled.
If that is the case, have you tried any of these? http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00820529&tmp_task=solveCategory&lc=en&dlc=en&cc...
By the way, even though Windows XP troubleshooting may not seem to apply to your situation, sometimes these sorts of errors and problems still happen in Windows Vista. It is rarer but it still happens. One Windows XP based solution can be found here: http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00035365&tmp_task=solveCategory&lc=en&dlc=en&cc...
Also, take a look at power management settings for your USB hub and/or USB ports. If they are enabled, try going to Computer Management, Device Manager, and then right click on the USB ports and select Properties. Following this, click the Power Management tab and uncheck the option "Allow the computer to turn off this device to save power" and click OK and exit out of Device Manager.
Odd as it seems, sometimes a restart is necessary for this to work completely.
Also, if you have tried removing the USB Hub drivers according to HP methods, you need to make sure that nothing is plugged into the Ports when you remove them. Often, a restart still is necessary even if some techs do not think to instruct you to do so. After a restart, allow the drivers to reinstall--all of them. Sometimes you still will need to restart your computer again afterward. This sometimes takes a few minutes. But, you must in any case make sure that nothing is plugged into the ports.
You may also want to check to see if your computer has specific drivers for your USB ports rather than the generic ones. If so, running the option for restoring drivers in HP Application Recovery will fix this. If they are there you will see the USB drivers listed.
On rare occasion, there is a problem with a device further down the tree than the USB ports and/or USB hubs themselves. These problems are most often fixed by removing the device that controls the USB Hub, such as the devices attached to the PCI Bus and connected to the USB. You will see where these are connected by changing the view to "Devices by Connection" rather than the "Devices by Type" option.
Let me know your status, please, after you have tried these options. If you have already tried them all out, let me know that, too and we can see if there is another option for you to try.

  • HP Pavilion dv6-6b10tx two of the usb ports are not working

    I have recently bought a HP Pavilion dv6-6b10tx....and had it fixed by hp for a problem with the beeping noise.
    After sending my laptop for repairs( replacing the system board), I received my laptop but two of my usb ports are not functioning...
    I did a bios update and did the hp update to see if it actually fix anything but not luck.  So I went device manager and found a exclamation mark on the renesas electronics usb 3.0 host controller with a device status 'This device cannot start. (Code 10)'.  What do i do??

    The question is why is the port not working?  Is something in the port that you can see?  If not, then there isn't much you can do but take the computer in to the genius bar and have the techs see if it is a circuit problem that can be fixed.

  • USB Ports are not working in Windows 7

    I am on a MacBook and I installed Windows 7 via Bootcamp. It is working amazingly. I love all the new features and the look.
    But all my usb devices are not working. I have a external HD and a Zune and a printer plugged in and nothing shows up.
    I have tried with my usb hub and without. Doesn't make a difference.
    BUT, they do show up in the Hardware and Devices place. Like I can remove them but not explore them.
    I have installed all the drivers for bootcamp and everything.
    Please help.
    Thanks in Advance.

  • Apple 23" Cinema Display - The USB Ports Are Not Working

    The USB ports on my Cinema Display are not working. I do have both Tiger and Leopard installed on my Power Mac G5. Does this issue have to do with Leopard? If so, how can I fix this issue?

    I would power down everything, disconnect the monitor from the computer, and the power from the computer and the monitor, wait 15 minutes, and reconnect the power. *Double check* your monitor connections, make sure the USB is properly inserted to the compters USB port. Might try a different port. If the USB ports of the computer work with known working devices (like a keyboard) and the problems continue, it looks like the monitor ports have a hardware problem.

  • Z87m gaming - 2 usb ports are not working

    Hello all,
    I have just finished putting together a new computer using the z78m motherboard which I am enjoying. I am running windows 64 on it. Unfortunately the two USB 3.0 ports under my lan port on the back panel are not working properly. Everything else works fine. I have installed the latest usb 3.0 drivers off the msi site. The BIOS does recognize those ports and indicates what is plugged in them. I feel like it still might be some sort of driver issue.
    In my system information, under components - Problem Devices , it lists Universal Serial Bus (USB) Controller ( error code - Drivers for this device are not installed )
    Then in my device manager, listed under other devices, it shows Universal Serial Bus (USB) Controller. When I try to automatically update the driver it says windows could not find one. I was thinking about manually updating it but I am not sure how to properly do that.
    There are a few options under USB Controller - Intel(R)
    - USB 3.0 eXtensible Host Controller
    - USB 3.0 Root Hub
    - USB 3.9 Hub
    - USB 2.0 ....... etc.
    I am not sure how to go about making a selection and I don't want to make my situation even worse. Wondering if anyone how there could point me in the right direction.
    Thanks!

  • HEAVY disk access and I can't figure out what's doing it

    Since installing Snow Leopard, I'm running into period of heavy disk usage (not idle). I can't seem to figure out what it is, because as soon as I get Activity Monitor up, it's calmed down. It's similar in usage to Spotlight indexing, but that's not what it is. The only thing I notice is the Quick Look Helper seems to at 16% CPU usage when this happens, quickly dropping below 1%. Anyone have any ideas of what I might look for? Is there a log I could check to see disk access?

    Hi,
    You could look at the Console.app in the Utilities folder and the 'top' command in the Terminal.app

  • My usb ports are not reading anything in plug in. new out of the box iMac

    i just took my mac out of the box and the usb ports don't seem to be working. i plugged in a gopro and an external hard drive. neither will show up anywhere.
    there is power going to them. what might be wrong?

    Worth a shot. Whats the harm.
    I'd not recommend it on a brand new Mac. That should be considered DOA. See this caution in this article:
    an SMC reset should only be attempted  after all other standard troubleshooting has been performed.

  • Why are you not working? I can't figure out why this works in 1 doc, and not in another

    I'm trying to take info from a cell on 1 spreadsheet and have it populate into a different one (pending if checkbox is true or not). I've been able to do it with 2 files but for some reason this one isn't doing what I need. If the checkbox is unchecked the text should stay in the new spreadsheet cell, if it's checked I want the row removed, but for reason instead of removing the row it just places a 0 in the cell.
    This is what I want:
    Like I said it works great on the other doc, just not on this new one. (the 2 docs vary with some of the text, but in the second image I've "checkboxed" out some of the text)
    Please help!
    Thanks!
    Nikki

    You may have the wrong cell reference  (B2) in the second part of your formula. If B2 is empty, the result will be displayed as a 0. Did you mean to have A2 in both parts of the formula?

  • I need to have a URL that's loading from a batch file load into the side bar instead of the main window and I can't figure out what to add to the command line to make it do this.

    I've seen similar questions, but no answers. Most commonly, I've seen people wanting to know how to code a link on their website to make it open in the sidebar. That would be handy too.
    My own goal here is to make all the pages I need open for work open where I want them, all in one click.

    I don't have a Recently Added playlist.  However, I discovered that the file I had named Eating Healthy was given the name You Can Enjoy Eating Healthy when it copied to iTunes.  I'm guessing iTunes pulled the full name of the piece from the internet.  Upshot--the mp3 did transfer to iTunes on all 3 tries, but I was looking in my alphabetized list under E, not Y, so I didn't see it there.  Thanks for your help.

    Did they also restore your original user account? Log out of Apple and see if yours is there to log in to.

  • My podcast isn't updating and I can't figure out why, please help?

    Hi everyone,
    I'm at my wits end and I can't figure out what's wrong with my podcast in regards to iTunes.
    We have a website we update that originally iTunes was pointed at (http://www.whydaddydrinks.net/?feed=rss2) and then iTunes started having issues with not updating. Recently we tried changing the feed of the podcast to the RSS feed for our podcast hosting account at Podbean (http://whydaddydrinks.podbean.com/feed/) and it's running into the same issue.
    I've checked FeedValidator for both feeds and they're fine (http://feedvalidator.org/check.cgi?url=http%3A%2F%2Fwww.whydaddydrinks.net%2F%3F feed%3Drss2 and http://feedvalidator.org/check.cgi?url=http%3A%2F%2Fwhydaddydrinks.podbean.com%2 Ffeed%2F). I've clicked the links to the .mp3 files and they play off the web, so, in theory, there shouldn't be any issue as far as I know; Episode 13 shows up in iTunes but dosn't appear to be connected to the file and Season 2 Episode 1 doesn't show up at all.
    Can any of you offer any suggestions as to what the heck is going on?

    Your Store page is at https://itunes.apple.com/gb/podcast/your-book-is-why-daddy-drinks/id515363310?mt =2
    This is using the feed at http://www.whydaddydrinks.net/?feed=rss2 so the other feed URL you posted is irrelevant.
    This feed has episodes up to 13 which contain playable media, and these all show in the Store and when subscribing. However the URL for the media file for episode 13 is
    http://media40.podbean.com/pb/89ea6f327345e33833ff09885e48b8a1/50e904db/data2/bl ogs48/462271/uploads/YBIWDD_Episode13.mp3
    and there is no file at this address. The previous episode downloads OK.
    This feed contains two later episodes but neither has an 'enclosure' tag containing the URL of a media file and so the episodes don't show in iTunes. You are using WordPress to make your feed, and this problem arises a lot - it presumably means that you have failed to do something you need to do in WordPress to get the media file into the feed, but I can't advise on specifics of WordPress.
    The other feed has one of these two episodes, and there the latest episode does have an 'enclosure' tag and the episode appears when subscribing manually; however as I say this feed is not in use by the Store.
    So you need to do with the original feed whatever it was you did with the new feed to get the episode into the Store, and you need to chase the missing media file for episode 13.
    If you want to move the Store to using the Podbean feed you need to follow the procedure outlined here:

    Note that the title in the Podbean feed is 'whydaddydrinks' which many not be what you want.
