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?

Please try this:

  • Notebook G71-358NR - Windows 7 64 bit - right USB ports not working not

    The USB ports on the right works more while the left USB port works.  A right port does not work when a flash drive is connected; the other right port provides a message "USB device not recognized" and get a line of "unknown device" in Device Manager under the expanded Bus USB controllers.  I finished all updates to Windows and HP, verified and updated all the drivers and the USB ports on the right still do not work.

A recent hardware or software change might be installed a file that is signed incorrectly or damaged, or maybe it's a malicious software from an unknown source. (Code 52)

  • All USB ports stopped working Windows 7

    Windows 7 Pro. All USB ports stopped working.  When I plug a usb card, windows makes the sound as it connects and the card gets power (light).  I see the map appear in disk drives in Device Manager.  The player does not display in windows Explorer or disk management.  In Device Manager, it has an exclamation point and says that the device cannot start.

    Strangely, I have a USB keyboard and mouse and they work very well.

    It's just the USB drives and chips and SD cards that are not displayed.

    I have:

    Reinstalled the drivers USB MB

    Flashed the BIOS with the latest version

    Tried to install the older USB drivers

    Tried to let windows find the driver.

    Still does not

    None of this has helped.  I ended up formatting the HD and reinstall windows from dvd.

    This revealed that my USB multicard reader was bad.  When I unplugged the problem disappeared.

  • USB ports not responding do not after windows update

    After a windows update in March/April 2012 all my usb ports stop working. The single port works now is the SATA USB combo.

    all I have this problem and know how to fix?
    Even a general difficulty just to get ports working again would be greatly appreciated.
    I've exhausted all other patches and now know that it is the windows update that caused the problem, so I'm forced to ask for help here.
    Thanks in advance for your time.

    Which has been updated by windows update is specific to your individual system, and if the USB failed in April you seem to have left ror a long enough period.

    Windows Update > history will show what has been installed.

    In a first time visit your manufacturers of PC and update or reinstall your chipset drivers.

  • Satellite A200 - USB Ports stopped working

    Hallo, I am DESPERATE for help, please.

    I have a Toshiba laptop Satellite A200 series with 32-bit Windows.

    My USB ports give me major problems.

    I use a USB Internet Modem on multiple computers and it works fine on all computers, including Toshiba.

    A month earlier, Internet USB would suddenly and constantly disconnect itself from the Internet, when I use it in the USB one. When I use USB port two, he recorded no more. The port does not have the device.

    Two USB ports work well when used by other USB products.

    I had always used Internet USB into the USB port, with a cooling for my laptop fan, USB 2 port. Now, when I insert the cooling fan, USB Internet disconnects and will not register, at least I have remove fan, remove and reinsert the USB Internet.

    I did the following:

    1. start an anti-virus
    2 uninstall, re-install and update all the drivers for the USB, chipset famlies, Internet Modem ports, EVERYTHING.
    3. I checked with my Internet provider, the problem lies in my PC, not them.

    I don't know what to do, I'm tired.

    Help, please!

    Now, when I insert the cooling fan, USB Internet disconnects and will not register, at least I have remove fan, remove and reinsert the USB Internet.

    I think that it is a problem of USB power.

    The USB 2.0 port provides 500mA, and in some cases more than USB ports can be connected to the same power supply to the motherboard.
    In case the USB device connected (in your case fan) would need more than 500 ma, it could be that other USB devices do not work correctly.
    I recommend you go to Device Manager and select the properties of USB controller.

    The last "Power Management" tab contains the option to turn off the device to save power.
    This option should NOT be checked. It should be disabled.

    Check it out.

  • 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.

    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
