Thread: Computer does not see any USB ports anymore

  1. #1

    Default Computer does not see any USB ports anymore

    I had RAM 512 Mb and it caused me very frustrating screen freezes. Usually just when I had someone almost on cross-hair/or on low bombrun, it froze. When EAF310_Arturo was visiting me I told him about my PC problem and he helped me to change my 512 Mb RAM to 2 Gb.

    Promlems start: my RAM ports are old type DDR. Out of the two 1 Gb chips bought only one was ok, the other was taken back by shop and refunded. We discovered the problem of one chip because when both were added the game at first started but then after 2 mins kicked out. Now there is no more problem with that. I have one 256 Mb chip and added the 1 Gb chip.

    When the shop completed their diagnostics and I got home with my PC that had by now 1,256 Mb RAM we started the Il-2 game and unfortunately my joystick didn´t work. Arturo checked and confirmed that the computer does not acknowledge that it has USB ports of any sort. Seems like all of them are lost somehow, I can´t use the memory stick, attach a printer or use the joystick.

    I´ve had previously the same sort of thing happened, that it does not see the joystick, but that it does not recognize of having it´s ports is I think first time.

    P.S. we also uninstalled one anti virus program since I use new one. It asked: uninstall all virtual devices and we pushed I think yes.

    Help needed, or at least some sort of a logical explanation. Otherwise I really start to be even more superstitious about my PC.
    If nothing works I will just take my motherboard down to a pistol range and shoot it to the bits and bytes level.

    Cool Re: Computer does not see any USB ports anymore

    I was informed of the trouble after the diagnostics. So if anyone of you loses all USB ports like I did and you are not a PC specialist then probably what to expect is that your USB controller is broke and you have to replace it. I have the USB ports attached to the motherboard so I cant change them, instead probably will have to buy a new block and attach it somehow.

    Still happy that I don´t have to replace the whole motherboard!

    Good, that they identified the problem. Now the challenge is to find the USB block. Will stay in contact.

    Find your USB hubs from System\Device Manager and Uninstall the drivers. Your operating system should then re-install compatible drivers on rebooting. If you're flying Windows

    If you're running Vista Service Pack 2 beta version this is a known problem. By me at least

    I once had USB problems because of low powersupply. Maybe with new RAM power supply is too low? Just a thought, but I have no idea if and how much energy RAM needs.

    One way is to switch off your PC and then unplug it from the mains for 30+ mins or so.

    Or you could put your motherboard CD in and re-install them from there.

    G:L.
    Couple of reg hacks may work if these don't, come back and ask I'll look for the reg hack.

    Thanks for hint! We tried it, the problem was - no such device (USB controller) in the device manager at all... But I'll keep this advice in mind when encounter similar problem in the future.

    no such device (USB controller) in the device manager at all

    You will need a USB device to be installed in a USB port first Arturo, maybe you left all USB devices not plugged in?

    Which operating system are you running mate?

    Please read this page carefully, even though it's for Vista...

    I have an Iomega external hard drive. P/N is 31641400. model is MDHD320-U. Used to back up for 3 computers. Suddenly
    ceased working for one of the computers - message 'Invalid drive specification' shows. Nothing has changed, and the other
    two computers back up OK.Comment posted on Feb 08, 2009
    Thanks for your response. The drive letter is still the same. In fact, I had a good look at what had been going on on the
    offending computer over the past 3 weeks, which was when the problem started. I found that a Java update had been
    installed. I therefore carried out a system restore to just before the installation of the update and, hey presto, the problem
    disappeared. Clearly, there is something in the Java update that interferes with either the notepad instructions or does not
    allow the Iomega drive to recognize the driver.

    Me either. Thanks for trying to help though.
    My issue fits the FAQ Step 5, D - Universal Host Controller or USB Root Hub has an exclamation mark. The problem here is
    that this is the problem with the same HDD on two different machines! The darned thing worked on one just yesterday! So
    I'm having a hard time believing that it's a problem with the USB Controller card. I just don't buy that as the problem.
    This is not making me a brand evangelist for iomeda

    could be a usb drivers thing, this really appears to work for lots of people under Vista (I mean LOTS)

    Registry angle...

    If you’re not comfortable with the registry, don’t do this!
    Solution:
    1. In the run command (Start menu bar) type “regedit” to bring up the Registry Editor.
    2. In Registry Editor, navigate to:
    HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\Curr entVersion
    3. In the details pane, double-click DevicePath.
    4. Add a semi-colon to end of the existing text, and then add the path to
    %SystemRoot%\System32\DriverStore\filerepository. The result should be similar to:
    %SystemRoot%\inf;%SystemRoot%\System32\DriverStore \filerepository
    Do not remove the %SystemRoot%\inf file path from the DevicePath registry entry.
    5. Click OK to save the new value, and then close Registry Editor.
    6. Open device manager, uninstall all unknown devices (right click, uninstall) so they all disappear from the list, then use
    the icon at the top to “Scan for Hardware Changes.” You’ll get a prompt to locate device drivers, click it, and you’re done.

    Thank you for taking the trouble to publish. Can someone who knows anyone in the Vista R/D Department forward this
    blog to them at Microsoft?

    force search for drivers
    Manage to find a more permanent solution that worked for me.
    After you insert a USB device:
    - do a manual search for drivers and point to c:\windows\winsxs
    - Vista will show some warning about drivers not being signed or something, ignore and click continue
    After 3 weeks of searching for a fix from many forums this option finally worked for me
