• 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.

• Internal card reader & USB ports stop working in Windows 7 64 bit - HELP

  This seems to be VERY popular problem between Vista and 7 users. I can't find the right difficulty any where. I have a HP Pavilion of D5200T running Win 7 Home Premium 64-bit. (I can provide more specific if necessary specifications). I read a few other posts in this forum with exactly the same problem as me, I tried the suggested fixes - most of them anyway - and my problem persists.

  This is the story of the kind: bought PC Cognac nine in June 09. It came with Vista Home premium 64-bit. On the front panel, I have the HP 15 in 1 reader cards and below that another panel with micro/headphones, 2 USB ports and 1 port Firwire catches. They all worked great worked great, no problem at all. I bought Windows 7 and improved in October 09. These two USB ports and card reader have been in place since then. I turn on the computer or restart works and they. Slide into a car SD, CF, whatever it is. Little green light turns on, windows automatically opens on the screen indicating the contents of the card.

  The card reader is no longer everything first. It may be 15 minutes later, perhaps hours. I slip on a map and still get the little green light but nothing on the screen. As if no card has been inserted. 2 USB ports will do the same thing, just much less frequently. I step a USB item and I have an error message saying: is not recognized or not installed properly. If I restart - they are all back to work very well.

  So... this problem only started after the Windows 7 installed, then it is clear to me is where the problem lies. When card readers or USB is in their State of non-working, I'll go to Device Manager and see that they are always listed, and there is no indicator of errors.

  This is what I remember by train so far, without success. I uninstalled devices from the Device Manager, driver too. I tried unplugging them from the card, restart, reconnected, reinstall. I tried different plugs on the motherboard. I can't find the latest drivers. The courses are MS 21/06/06 6.1.7600.16385. I think I tried all utilities integrated in Win7 to try and diagnose, and none of them produced no results. I tried to disable the sleep function. I even reached out to HP support, and the best they have resulted so far is that the card reader is bad. They are sending me a new, but I do not think that this problem will be solved.

  As I said, I see this problem or similar to many, many forums but I have rarely seen a happy ending where it was fixed. Someone at - it the key? Help, please.

• 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.

• USB ports stopped working after the installation of the HP dv6-1053d, Win 7 printer.

  Removing the battery, restoration and by default the bios have been made, but no luck.

  Looks like you have tried all the stuff, all I can suggest is to backup your data and perform a recovery of HP.

• 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.

• 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.

• 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.

• laptop keyboard stopped working after Windows update.

  have a toshiba satellite A505 laptop and the keyboard stops working after Windows Update reboots. We reinstalled Windows 7, which fixed the problem until the updates have come. Now the keyboard is unresponsive. Sounds like a software problem, no material. Also checked the keyboard drivers that are up to date.

  As a first response, go to the control panel, device, keyboard, keyboard Manager and right click, uninstall it and let it rediscover Windows and then reinstall it.

  It suits it much of the time.

  I have some Toshiba laptops, satellite and now netbook100.

  All share a problem, the touchpad scroll bar:
  It stops working after you exit the full screen in youtube.
  Here's how to reproduce the incident:

  1. with the help of any mainstream browser, start playing a video on youtube, click on the button at the bottom right of the video full screen.
  2. click on [the cross] to exit full-screen. (next to button full screen.)
  3. check if you bar scroll that still work.

  The search in google (scroll touchpad bar stops full screen youtube) return more people will share the same question but no answer.

  Environments: win xp all, win vista all.
  All decks, Windows Update driver, updated touchpad driver.

  This is not a major technical problem, but for a netbook, it's very annoying.
  If anyone has this problem or answers, please share it here.

  Thank you in advance.
  Kind regards.

  To be honest, it's the first time I read on this issue.
  I m not a NB100 owner but I have a laptop and I m using IE as your browser and Windows XP.
  I checked this and my touchpad is not working correctly!

  I m wondering if this behavior would appear only the website youtube?  :|

• USB mouse stopped working after system update

  I'm running Windows 8 here and it updates automatic system has run and disabled use my connected USB mouse (manufacturer: Targus | model: AMU4201EUK)

  When I search the drivers in Device Manager tells me I'm using the latest drivers available and can't seem to find a driver for this specific mouse online.

  I use an external keyboard connected via USB and works without problem so I'm lost as to why the mouse would stop working. He able to go to the mouse as the LED inside turns on when it is plugged. Windows made his usual sounds when its connected and disconnected from.

  This happened last week and to work around, I restored windows since the eve of the update and it worked without problem. Windows tries to install the updates again after a few days, then the mouse will become unusable. I've lost the ability to return to this State, now I'm sure that Windows has replaced something in this update.

  The mouse uses of Microsofts HID drivers that are up to date and I confirmed the mouse works on other systems and on my laptop USB ports are functioning normally.

  Any suggestion is appreciated.

  Have you had a look in Device Manager for errors with USB devices?

  Use the Device Manager and uninstall the concentrators root USB and devices which show now on your machine.  Restart and let XP rediscover and see if that solves your problem.

  If you uninstall the mouse in Device Manager, then reboot, Windows should find the mouse and install the appropriate drivers.
