Windows 7 does not recognize USB devices. Have no system access keyboard or mouse.

Separated from this thread.

It is a question.  I have a Windows 7 laptop.  It has three USB ports.  They always worked perfectly.  Today, one of them stopped: Port_ #0001.Hub_ #0002

A sign of error says: "unrecognized usb device".  Troubleshooting, said that there no problem but under properties of the device, he says that Windows has turned off because it has detected a problem (Code 43).  I tried to plug in several things: camera, various readers flash, mouse, etc. They all used to work properly until today.  Now, it's just a dead port.

Hi Seiberte,

Thanks for posting the request in Microsoft Community Forums. I appreciate all the steps you tried to solve the problem.

What is the brand and model of the computer?

A device driver has notified the operating system that the device failed. This situation can occur if the peripheral equipment fails or if the device driver fails.

To resolve this issue, follow these steps.

  1. To open Device Manager, click Start, click files, and research programsand type Device Manager. A list of the available items will appear above the search box; Click on Device Manager. Device Manager opens with the name of your computer to the top and a list of the devices installed on your computer under the name of your computer.
  2. Locate the device in the list of devices, right-click on the device and then click Uninstall. When a warning message that you uninstall a device in your system, click OK. Device Manager uninstall the device.
  3. Right click on the name of your computer in the Device Manager, then click on Search the hardware changes. Device Manager scan your system and reinstall your device automatically.
  4. Right click on the device, and then click Properties. The general of the device, in the State of the device Properties dialog box tab, you should see the message this device does not work correctly.

If the steps above do not solve problems with the device and the device is an external drive, such as an external hard drive or USB flash drive, use the icon of the taskbar to safely eject the device, and then disconnect the device from the computer. For devices that use AC power, unplug the unit from the wall outlet or the power strip, wait 30 seconds and then plug it in again. Turn on the switch of the device and then plug it into your computer. If the system includes a driver diskette, ensure that you have at hand to install device drivers; otherwise, Windows should automatically locate the appropriate drivers and install them.

  • Qosmio F30 does not recognize USB devices

    My new Qosmio F30 does not recognize USB devices. Displays Device Manager USB ENHANCED CONTROLLER and ROOT HUB works fine, but the machine still wants to install each device but cannot. BIOS version seems to be V1.30. I tried the devices on other machines, and they work fine.
    Is there something that I missed?

    Hello

    Before your shot the beautiful F30 can you please say what OS you are using?
    Did you use the OS from the Toshiba restore CD?
    On this CD, all drivers must be preinstalled and you don t need to install no matter what chipsets or anything like that.

  • Satellite A30: Does not recognize USB devices.

    My computer does not recognize any devices when connected to the USB Port on my Satellite A30. After downloading SP2, I was able to install the printer, but I can't use it because there is no printer icon in the toolbar. If I want to print something I get the window of the printer, select printing, then it goes to the author of the Image of MS Office. Basically, I can't use my printer or any other device connected to a USB port.

    However, it was working perfectly fine when I had the home edition of XP but I can not reinstall this one because there is something wrong with the recovery disk that's why I had to install XP Pro.
    Also, I used to get a sound, letting me know that a device has been connected. I get more or the icon in the toolbar.

    Is that what I could do to fix this please? Is it possible to get another disc of recovery somehow? Obviously, it's something to do with XP Pro software, but I don't know what to do.
    Could you please help me?

    Thank you!

    Hello

    If you get a window of the printer you need to select the right printer. If printing goes to MS Office Image writer so the right printer is not selected.

    On the new installation: If you install the operating system from the original Windows CD you must install the necessary drivers and QFE patches all in the right order.

  • Satellite L50 - B suddenly does not recognize USB devices

    Suddenly my laptop does not recognize any USB.

    The USB key or external hard drive works on other computers, but not on my laptop.
    Only cards SD-are recognized.

    I tried to remove the usb portals on the Control Panel, but after I restarted my computer all returned.
    One reappear with a caveat that it does not work, but when I search a new program to run it, it can not be found. After removing it, it comes back with the same caveat.

    I also tried to download the new discs (chip set utility) but who doesn't either.
    I don't know what else to do.

    Can someone help me if I can access my USB-products once again on my laptop?

    Hello

    What about the USB mouse? You can use the USB mouse connected to one of the USB ports?

    Have you changed the system or you have installed new OS on this laptop?
    I m asking because the L50 - B Satellite supports USB 2.0 as well USB 3.0 ports

    In the case where you have installed the new OS (Win 7?) on this laptop, the USB 3.0 ports would require additional USB 3.0 driver

    However, in case that you are always using the OS preinstalled Toshiba, I recommend you to reset the initial setup and test the USB ports once more.

  • Windows 7 does not recognize usb 6221

    Hello

    I had a request (more the whole package with DAQmx and Runtime) in Labview that is deployed on more than one PC. So far, it works great on the PC with Windows XP.

    Now, I have to install the same application on a PC with Win7. The problem is that the LabView can not recognize the USB6221 Council.

    In the Windows Device Manager the jury is there, but LabView sees nothing. Also, if I check in measurement and automation, I don't see the jury. I have installed and reinstalled the whole software but no results.

    Does anzbody had the same experience or someone could give me some advice?

    Thank you

    Paul

    Dear Pauline,

    There are some factors to take into account while porting on windows platform 7. As far as I know, only the software labview 2009 are fully compatiable with windows 7.

    Which means a move to windows 7, you will need the following.

    (i) the runtime Labview (Labview 2009)

    (II) any compatiable (DAQ, DAQmx) drivers with windows 7.

    (III) created by labview 2009 exe.

    The last time, I also face similar problems. I build the exe in windows Xp (Labview 8.6) platform and I can ship to the Vista and windows Xp platform. However when I port the exe for windows platform 7, I also can't operate well after many trials.

    Finally, I upgrade to Labview 2009 and compile the exe under windows platform 7. Send this exe with the lastest drivers (drivers for windows 7) and my exe works well for all platforms (XP, Vista and windows 7) now.

    Maybe it's something you love to try.

  • Qosmio G30-163: encoder Windows media does not recognize video devices

    I can't get the Windows media encoder to recognize my video camera connected to the S-video (Qosmio G30-163) port.

    I have a similar problem with Web conferencing pro application Marratech (it crashes after 15-20 seconds if I try to use it-during the time the application is inactive - in configuration I see the photo/video test).

    If I use InterVideo® WinDVD Creator 2 Platinum software packaged for video capture it works fine.

    Hello

    In my opinion there would be something wrong with the compatibility of the MCE and s-video. Have you tried to run the MCE updates?
    If the s-video connection works with InterVideo WinDVD Creator, then I guess there is no hardware malfunction (s-video port).

    How about the video and the port? Have you checked if it works?
    This port allows you to import video data from analog video camera.
    I recommend you this option

  • Satellite A300 - Windows 7 does not recognize external devices

    Windows 7 (32-bit) an upgrade of Vista and couldn't be more peripheral to work due to driver problems. Talked to Microsoft and they found that my drivers are still there but can not find them unless I tell them where to look, and so all devices I plug I need to install drivers for both times.

    Any body have ideas how to solve this problem?

    Hi doug47,

    To be honest, I think I can t help you because I know you want to know exactly.

    External devices, you mean? Not everything you need drivers, like external hard drives, USB sticks, etc. These discs will be recognized automatically (plug & play) and they are read to use after connecting.

    If you mean printer or mobile phones you have need of additional drivers. You can get it from the manufacture.

    UPDATE! I used a different USB cable and the problem disappeared. That would be the life that were easy!

    Hi Michael,

    As you mentioned, the problem disappeared using another USB cable, it means that the USB cable has gone wrong.

    You can continue to use another USB cable to connect the Canon 40 d SLR digital.

  • Computer does not recognize USB devices after startup XP

    What type of laptop do you have?

    Hello Graboots,

    Thank you for your message.  You can plug your printer on another computer, in order to exclude the possibility that the problem lies in the printer?  You can try using a different cable, for this rule as well.  Since it is a question of recognition, we remove the external devices before software troubleshooting.  Do you get anything when you plug the printer (ie. a tinkle of connection)?  Please let us know, we are looking forward to hear back on your part.

  • Statellite M100 does not recognize USB storage devices or SD card

    I had problems with my laptop Toshiba Satellite M100 series read don't not Sandisk SD card in the camera to my son - is a 2 GB card and what I read online, maybe that is the problem BUT the laptop is also not reading any of my devices USB "stick". When I insert the SD card or a USB 'stick' he asks me to install the driver software that is simply stupid. I tried to connect the camera via a usb cable too and it does not recognize the device and still once, claims the driver software device.

    I looked on the toshiba site and have installed all updates that I thought may be justified, I'm also trying to run Windows update (at least every 2nd week anyway so it shouldn't be a problem). I am running Vista Home Edition (32 bit). The USB ports have certainly worked in the past, I don't really want to resort to execution of recovery discs if I have as I don't want to lose all the stuff I've stored.

    Question of the SD Card/USB seems to be a common one, but I can't find a specific patch to this topic or any other tech site, any suggestions?

    See you soon

    In your case, I would do two things.

    First: Check if a new BIOS is available. Search on the Toshiba site and do an update.

    Second: Reinstall the laptop with the recovery discs. I know that you will lose all the data, but you can save it to s DVD or external HARD drive.
