• Qosmio F60 - USB ports stopped when I'm with them

  H ? !

  I have a problem on my Qosmio F60. I opened my computer after 30 or 40 minutes firstly, 2nd and 3rd usb ports stopped after 5 minutes 1 usb port stopped and I can't use them. When I started my active computer, usb ports and they start working.

  I checked my power plans and no problem with them. I think that the heat of my computer too well maybe, I'm not good. Can help you me with the usb ports on my computer. Show

  Hey,.

  I put t think that the problem is related to overheating. If the USB ports stop working I think that it s a software or driver problem

  In your case I would remove all the USB ports on the Device Manager and restart your computer. The ports will be recognized again, and then test you its operation.

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)

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

• 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.

• 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.

• Satellite P850 - right USB ports stopped working

  I have a new P850 Satellite, after a short period, that the two right usb ports stopped working, I had only a wireless mouse connected to them at the time. Is there a reset for these ports, I tried to uninstall and reinstall, no change.

  Anyone has any ideas.

  > I tried to uninstall and reinstall, no change.
  What have you tried to uninstall or reinstall?

• Satellite C650 - USB ports not recognized in Device Manager

  When I turned off my cell phone, I lose the use of my two USB ports. The only way I can get back them is to use Device Manager

  Go into the Manager of peripheral devices, Bus USB controllers, there are 6 x Intel ICH9 Family USB Universal Host controller 2 x Intel ICH9 Family USB2 Enhanced Host Controllers and 7 x USB hub root. When I lose the USB ports, USB root hubs seem to disappear, and the only way I can get back them is to uninstall the controllers and then right-click Universal Serial Bus Conrollers for "scan for changes on the hardware. This brings back the root hubs and USB ports work fine... until the computer turns off again.

  Someone at - he encountered this problem and managed to resolve it? Its a hassle to have to go through the uninstall it / Reinstall procedure each time. Your advice will be appreciated.

  Hey Buddy,

  You use the version preinstalled Windows from Toshiba or did you install your own version? I don't see any information about the BONES in your ad...
  Theoretically, it could be a software problem so ports USB work correctly if they recognized in Device Manager

  You should also try to update the Web from Toshiba site chipset driver. Maybe it helps.
  Otherwise, I could imagine that the update of the BIOS can also operate and this update you can get on the Web from Toshiba site too.

• 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.

• USB ports not recognized anymore

  I have Vista.  USB ports and ports that accept cards camera no longer recognize them.  Scanner can be moved from USB port to the USB port and works but "Explorer" does not show that they exist.  How to recognize camera cards (mainly) as they did before?  Windows offers device (camera card) has a problem, but this isn't the case.  Card works so executed through camera (USB cable to the USB port) in two different cases with two different cameras.  Also plugged on the USP port scanner is not recognized by the function 'Explorer' but actually works very well.

  Hello ghpots,

  ·         What happens when connect cards camera on USB ports, it installs the device drivers?

  ·         What are the changes that you made to your computer, since it has stopped working.

  When you connect your devices to the USB ports, check the status of the device in the Device Manager. Check if you see a yellow fringe or exclamations in the Device Manager.

  I suggest that you remove and then reinstall all USB controllers.

  To remove and reinstall all USB controllers, follow these steps:

  1. click on start, type Device Manager and open the Device Manager.

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

  3. restart the computer and reinstall the USB controllers.

  Plug in the removable USB storage device and test to make sure that the problem is solved.

  Check the Device Manager to see if the unit under section USB or other devices. To do this, follow the procedures below:

  Method 1:

  1. click on Start, right click computerand select Properties .

  2. click on Device Manager.

  3. click on the (+) sign next to Universal Serial Bus controllers and next to the peripheral plus other section.

  Look for the USB device under the Universal Serial Bus controllers, or under the other devices section.

  4. If the unit is under Bus USB controllers or other devices, click on the reference to the 'unknown' device name, and then click Uninstall to remove the device.

  5. close Device Manager, and then restart the computer.

  6. If the USB device that has problems with software and it has not already been installed, install the software, now follow the planned manufacturer of the directives.

  7 reconnect the USB device that had issues and test to see if it works.

  The unit should now work correctly. Continue if the device name is not found in the Device Manager.

  Method 2: There may be a problem with the USB port. Try connecting to a different USB port. If the USB device is displayed in Device Manager after plugging the cable in a different port, then uninstall and reinstall the software of USB device driver.

  Method 3: Check the manufacturer of the device for support if the device is still unable to display.

• all 3 USB ports stopped working - MX30

  As a result, none of the 3 USB ports on my old MX30 work of 2 months. I unchecked the option in the hardware Manager of devices for energy saving, nothing helps. First of all, only the mouse stopped and I thought the mouse was to blame, but all of a sudden the machine does not recognize the USB memory key more.
  Any advice would be very welcome, because I can't work!

  Respond to my ad. I've updated the drivers for the USB host controller and BIOS and USB ports running again.

• SQosmio G50 - 10 H - one of the usb ports stopped working

  Hello forum,.

  I have a BOUNCING problem with usb ports on my qosmio g50-10 h.
  There are two ports on the right side of the machine and I have 2 self-powered 7 centers of port (usb 2) attached to these.

  Every now and then to stop it from ports and of course all the parts a unregcognised, not found.
  I get error messages saying unregognised device or usb device stopped working or windows stopped device etc.

  Unplug the hub and repluging it ususally actually come back to life.

  any ideas?

  Stafford

  Hello

  Have you tried to connect devices directly to the USB port?
  Try this and see if the USB device is disconnected, as you mentioned that using the external USB hub.

  Generally speaking, it is difficult to say what might cause this
  You could try updating the chipset driver.
  Of course, you should also check the USB port settings, and power management options for economy.

  In device manager-> USB root & hub-> properties you could disable for unique energy saving USB ports.
  This also on Win 7 power management.

• 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.

• Satellite L850 - USB Port stopped working

  Hello guys,.

  first sorry for my bad English, im from Germany.

  My new clearly L850 satellite has had some problems with sound-Port USB.
  I think it's the Usb3.0 Port on the left.
  While I'm workin with an external keyboard, the USB Port has stopped working and cannot identify the keyboard.
  All other devices that I put there, are out of order, but when I put an external hard Powerdevice with separate data for laptop, that he is there something ist connectet, but can't identify it.

  I have try all troubleshooting close it, like install new drivers, disable ports and restart and any kind of it.

  So maybe you have another tip for me?
  Or do I have to bring my laptop to the store for warranty?
  A Windows 8 64 bit on it, maybe it will help.

  Best regards, neothic

  Have you tried reinstalling the driver USB 3.0? Please try and check the functionality. If this will not help I recommend you do the ultimate test: back up all your data and reinstall Win8 using recovery media. Test it with clean OS preinstalled and factory settings.

  In the worst cases, you should contact the nearest Toshiba service provider and ask for help.
