• 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.

• All USB Ports stopped working, the software device driver has not been installed successfully, error code 52

  Hi I do not know what the problem with my USB ports I can not connect to any device, do not know when he started since week last I have no problem with that, I thank you for the helpful answers!

  Can remember you if the beginning of the problem coincided in the installation of Nero?

  Also, have you considered, or it would be convenient to use the system restore using a restore point before the beginning of the question.

  Another possibility is to reinstall or 'repair' Nero over himself.

• G1 laptop computer 350. All USB ports stopped working

  Hello. I hope someone can give me some advice on this subject.

  I turned on my laptop the other day and none of the USB ports worked. Any device I plug is not recognized and there is no power to the USB ports. (Goal of mouse does not light, bright external HHD is turned off. USB flash drives do not light up.) Powered deviecs are not also recognized is more than a problem of USB power. (When I say not recognized I mean there is no indication that they are still connected, no pop up error message or indication in Device Manager that the device may be defective).

  I tried to uninstall all USB drivers without result, I started from a Linux CD and a Win7 ERD without result. I also tried a hard reset, also without result. I have reset the BIOS and verified that USB is enabled in the BIOS but that also made no difference.

  If anyone has any useful advice, I would be very grateful.

• USB ports stopped working unexpectedly

  Hi, I am currently on "Toshiba Satellite C655"run"Windows 7 Home Premium". It's a laptop of 2009 model (2 GB). Last night (24/02/14) my USB Ports stopped working, they have been and continue to read anything every time I have to plug my devices. I usually only connect a cooling block and a USB mouse to the computer. They worked perfectly until I disconnected the. When I reconnect them, they work momentarily, and then I hear the beep sounds when you eject a device. I tried to connect several flashdrives, a printer, and one I tried the following hotfixes:

  Note: The order of numbering has nothing to do with the order, I tried to apply each patch unless specified elsewhere. This computer had Windows 7 Home Premium REINSTALLED at some point. Just for your information. This message was made when there are others with the same problem is due to the fact that no solution not specified by Microsoft Technical Support or the Microsoft community were effective.

  1) System Restore to the last known point, where they worked (and still). (Point restoration @ 15/02/24)

  2) Windows Update

  3) turn off the computer, disconnect the battery and the power supply and holding 'On' button for 10seconds.

  (Note: whenever I turn on the computer now they work only for a moment, usually from 60 to 180 seconds.)

  (4) Start > research ' Device Manager '> "De Bus USB controllers" Expand and turn off and restart the computer. They are re - activate automatically but my problem persists.

  (5) download and run "Microsoft FixIt.WinUSB... ", on the 1st, I had a problem with devices not updated. But I actually watch updates by using Windows Update and ""searching for hardware changes "" on USB Bus controllers "." I then did a 'System Restore' and now Microsoft FixIt found no problem but the USB Ports don't always work.

  (6) will ' services.msc"and change the Startup Type of Manual to Automatic for Windows install and restart Windows."

  7) regedit

  8) sfc/scannow

  I am really lost with this problem now. My laptop works and worked perfectly fine until this problem occurred. I have fixed minor problems with computers before, but this is a bad joke for me now. If someone could please help me with this problem I would appreciate it a lot. Thank you very much.

  Thank you for your help, but I discovered something funny on my computer. My cooling package (product name: Laptop Cooling Pad NSB;) HYCF-6181-2 model number) is to disable my USB ports when I plug. If I leave it unplugged and restart my computer, my USB mouse is still working on a port. Also tried using my USB and other devices. The problem is my block of cooling that strangely disables my USB ports, whenever I plug. Thank you very much for your quick response, fortunately the answer might help me in the future. For now, I have solved my problem.

  Hello

  Before you try this, unplug the devices all attached, turn off the PC and remove the power plug.

  There should be a jumper on the Board that you can use to remove the settings current CMOS, located just above the cmos battery - move the jumper to the clear position for 30 seconds and then bring him back - see the image at the link below.

  Assuming that your keyboard works during boot (and it should; trying to tap F8 to access Advanced Boot Options Menu), probably the simplest method would be to make a Hiren Boot CD, boot from it and use one of the many included tools.  I have not experienced with your particular situation, so I can not tell you what tools will be or will work for you, but my guess is that USBDeView might work.

  Thanks for all the help. Seems that there is no easy 'reset' for bad hardware configurations.

  However, I dug to the bottom of my Lac 'tech' and found a USB-to-PS/2 adapter, which allowed me to use the USB mouse into the PS/2 port and reactivate my USB ports.

  All is well now.

  Thank you all for your answers!

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

  Method 2:

  Uninstall all the USB controllers, download the latest USB driver on the computer manufacturer site, install on your computer and check the status of the issue.

  Remove and reinstall all USB controllers.

  a. to remove and reinstall all USB controllers, follow these steps:

  b. Click Start, run, type sysdm.cpl in the Open box and then click OK.

  c. click on the Hardware tab.

  d. click the Device Manager button.

  e. expand Bus USB controllers.

  f. right-click every device under the Bus USB controllers node and then click on uninstall to remove them one at a time.

  g. restart the computer and reinstall the USB controllers.

• Device not recognized USB error message - all USB ports.

  Apologies if all this seems a bit simple, but I'm not an expert, so bear with me.

  I have a laptop Fujitsu Siemens Amilo Li 1718.

  My USB ports have stopped working in 2-3 weeks.  I get the message "USB device not recognized.  One of the devices attached to this computer has malfunctioned and Windows does not recognize... »

  I don't seem to get any yellow exclamation point in device, all my drivers in Device Manager and software are up to date and Windows Update is running.

  My mobile phone and ipod always charge when I plug them in and out of this problem, everything works fine.

  In addition to the usual updates of Windows, only two other things have occurred since last, they worked.  One was that I renewed my subscription to Norton Antivirus, the other was that my laptop battery ran right out while he was in mode 'sleep' as I did not know that I had not plugged to the socket properly.

  So far, I went through some process as suggested by various items and/or help & support on Microsoft.com.  They include:

  * (From multiple locations) system restore has failed.
  * Diagnostic software Ran Fujitsu Siemens, which says that my computer is fine.
  * Run the virus scan who come clean.
  * Tries to connect via a USB hub.
  * Deletied the USB controllers in Device Manager to re - install.
  * Changing the settings of ForceHcResetOnResume 3-to-1
  * Change AdditionalCriticalWorkerThreads from 0 to 2

  (The last two I've changed back again after neither worked).

  My opinion of beginner, it's that looks like it will create new registry details for each device when valid seem to exist already is not thankful.  Although given my lack of technical knowledge, this could well be stating the obvious.

  So, now, I drew a blank.  Anyone got any ideas?  Got 9 months left a 3-year warranty, I don't want to go through the hassle if it can be avoided without too much trouble.

  Thanks in advance!

  Here is the similar procedure under XP, Vista is the same, except that we need to clear the specific device if present.
