USB ports not working no-Windows 7 on Imac

• USB port not working after Windows updates

  My laptop does not recognize a USB device I've used in the past.  If I restart the computer after trying to plug it, I get a system repair and it cannot solve the problem.  The only way I could fix is to do a system restore in Sfe Mode, to a point, 2 weeks ago.  The only changes since then have been Windows updates.  How can I fix it

  Restoring the last known time that everything worked as you want!  Check that it works.  Then start to install the updates at the same time with restarts and tests in between.

• 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?

• 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.

  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.

• 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.

• USB ports stop working after windows 7 updates (April 12, 2011)

  After application of the 12 updates successfully (KB890830, KB2508272, KB2506223, KB250212, KB2508429, KB2507618, KB2509553, KB2503658, KB2506014, KB2491683, KB2511455 and KB2446710), my USB ports stopped working after restart. I get this description of Device Manager: Windows cannot verify the digital signature for the drivers required for this device. 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)

  I restored the functionality of USB ports by doing a system restore before installing updates.

  What should I do? Ignore ALL updates future windows 7, which leaves the system vulnerable? Help is appreciated thanks.

  I solved this.

• Z500 8.1 Windows 64-bit USB ports not working not

  Hi everyone, now I have bought a lenovo Z500. After update to 8.1 Windows 64 bit, USB flashdrives could not run properly eventually Explorer Windows did not. When I try to restart, it blocks on the screen "Restart" and I have to press and hold the power button to power unit off which is very dangerous for the laptop. Other usb devices work well as a drive external hard, mouse and keyboard. USB flash drive only have such a problem. When I insert my USB key, I hear the sound which indicates that a device has been inserted. It is not the usb flash drive, because I tried with different USB keys and the same thing happens. All USB keys works well on my desktop (Windows 7).

  Thank you..!!
