  Hi waly,.

  Thank you for the information. I suggest that you unplug all USB connections and refresh your laptop. Then try to use your webcam. I think that the problem with the USB connection that gives you the error and not your webcam. Here is a document on how to update your PC to solve problems (Windows 8).

  If you are still experiencing a problem with the webcam and then one of the documents in the previous post should help now. Any stage of document Windows 8 will be the same for Windows 8.1.

  I'm also including this document how trouble Code 43 errors that will help determine which USB product causes the error to appear.

  I hope that this information help, please let me know how it goes.

  Good luck and have a great day!

• Tecra S2: HDD as unknown device on two of the three USB ports

  Hey again,
  I thought then that I was here anyway I could ask this too.
  The tecra S2 has 3 USB ports, they all work very well for my USB mouse and other small things like the wacom tablet...
  But when I plug my external hard drive in two of them, it says that it is an unknown device...

  I think, but am not sure, that this might have something to do with something once, we had to do in school;
  We had once set up a pilot for a small converted Converter a series (or parallel, cant he recall) cable to the usb port
  (I have already uninstalled the drivers but nothing has changed)

  It's just a guess...

  any idea on how to solve this little problem? : p

  Hello

  You said external USB HDD appears as an unknown device on two of the three USB ports.
  What appears if you connect the HARD drive to the USB port on third?
  It appears as an unknown device or what?

  The device usually appears as an unknown device in device because manager not installed device drivers.
  I check the HARD disk for the drivers and try to install it again.

• PIXMA MX340 Windows 10 device descriptor request failed Code 43

  Hello.  I recently bought a new computer to office 810 - QE HP Envy Phoenix yesterday.

  The first thing I did was to finish the free update on a clean slate ("save anything") of Windows for Windows Professional 10, 64-bit edition 8.1.

  The specifications of the system are:

  32 GB RAM DDR3
  3 TB hard drive 7 200 RPM SATA
  Integrated Realtek / Beats Audio
  Processor Intel Core i7-4790 3.6 GHz 4 hearts

  NVIDIA GeForce GTX 745 4 GB DDR3 video card

  My Canon Pixma MX 340 multifunction printer is not able to be recognized by this new system.  I installed the software and drivers for the printer, however, Device Manager keeps telling me that this printer is a "unknown USB device: device descriptor request failed, code 43"  I also tried to download the latest drivers directly from Canon specifically list of compatibility with Windows 10, which did not help me at all because the drivers are not able to find the printer during the installation.

  I had originally this printer connected to one of the USB ports 3.0 at the back of the system, but I have also tried using this printer with the USB 2.0 ports, as my old system had USB 2.0.  No change, it still gives the same exact error.  I also tried this printer connected directly to the USB 3.0 and USB 2.0 ports on my computer without effect before.

  I checked to see if this printer is "compatible" with 10 windows, and according to the compatibility of Microsoft website, it says that the Pixma MX340 should compatible.

  Advice, tips or suggestions would be very appreciated.  Thank you.

  I FOUND THE PROBLEM.

  I forgot that not only I used an extension USB cable, but I was also with a long USB cable and the USB extension as well.  This long USB cable was the culprit!

  I just noticed this and decided to test it.  With the long USB cable, I get the error. But when going back to a standard length cable, the printer was correctly as a Canon MX340!

  If I switch back to the long cable, it will be impossible to find.

  However, I can still use the USB extension cable.  This cable does not cause a conflict any!

  Hello j_waver0000,

  Thank you for using the Microsoft Windows Vista Forums.

  I would like more information on what brand and model of mouse you are using?  I know that you listed Trackball, but I show several manufacturers using the name of trackball, including Microsoft.

  Have you informed you have uninstalled the mouse drivers, have you done this in Device Manager?   "Click Start-> type Device Manager" in the search field-> select Device Manager-> select mice and other pointing devices-> with the right button of your device, and then select update.

  If the device is already updated and then right-click and select "Uninstall".  You may be prompted to restart, otherwise right click again on your device and select "install".

  If you have a Microsoft Mouse, please visit this link for additional information.  Please let us know status.  Thank you!

• Unknown device in the device error 43 Manager

  I get a 43 unknown device error when I start Windows 7.  I tried every fix I found after ten days of research.  When Windows starts, and the notification is popping up that I can't use my keyboard are so difficult to do anything.  Finally, the message disappears (I don't know why) and I am able to type, or if I catch it just just between notifications.  At this time I started my computer in clean boot mode and no error message appears and the unknown device is not USB device controllers manager.

  What, in my view, that has happened, is that I used to have an LG phone and the software on the computer.  I now have a new phone, Samsung, that I just connected to the same port on the front of the computer.  The Samsung worked, but did not ask me to install the software, then must have run out of the LG.  I deleted the software from LG and then reconnected the Samsung and got the prompt to download the correct software.  I then plugged a generic USB hub device in order to use the phone and any other device that I could plug in (none at this time and I even unplugged the generic hub).

  Now I get the unknown device.  Some fix told me he didn't need a driver, but Windows keeps load a generic driver and so the message repeats the process over and over again.

  Unknown error seems to be a common problem, probably a fix is available from Microsoft.

  Any help would be appreciated more because it drives me crazy!

  Thanks for your reply, Al-Shabaab.  In fact, I solved the problem.

  I deleted all the Verizon and Samsung software on my computer.  When doing this, I noticed that my keyboard has gradually deteriorated (failed to start in safe mode F8 key would not work).

  I bought a new keyboard... and EUREKA!  Problem disappeared!  Then I rebooted my phone software and have had no problems since.  I guess it was a coincidence that the keyboard was dying as I tried to connect my phone to my computer leading me on a GOOSE Chase that was long, difficult and extremely frustrating!

  I appreciate the help and I hope this will help others.

• Satellite M50D - A - 10 L - pilot missing for unknown device

  You just bought a Satellite M50D - A - 10 L and after 1 week, the HARD drive failed. Of course, I had to replace on my spending, because the guarantee would be in about 2 weeks, which was too long to wait for me.
  In any case, I also lost the pre-installed Windows 8.1, but is not a tragedy, because I reinstalled it and everything works well.
  The problem I have I have one of the pilots is not recognized by the "Device Manager". The device is called 'Device ACPI'. Any idea which driver missing is all about?

• "Unknown device" USB Barcode scanner, problem with the USB controller driver?

  Hello

  I need assistance with our Barcode Scanners that doesn't work on our newly purchased computers at HP with Windows7 Pro x 64 operating systems.

  The brand and model of the bar code scanner is:

  Datalogic Heron D130 USB.

  When you connect the scanner to a USB port, Windows will try to install this as a HID, but it takes an unusually long time, about 7-8 seconds, to boot the device and install the drivers and appears as an unknown device in windows "devices and printers" and the hand scanner does not work.

  Sometimes when you move the USB back can I sometimes the scanner at hand to be recognized as an HID device or a Datalogic barcode scanner,

  It works fine until you restart the computer.

  After restart the computer cannot detect the scanner Barcode correctly without re - appears as unknown device.

  I suspect that there is a compatibility problem between barcode scanner and card USB controller on the computers.

  I tried to update all the drivers available on the website www.hp.com and same www.Intel.com (chipset drivers) but nothing has helped to solve this problem

  Tried newly bought barcode scanners and "used" barcode scanners earlier who works on other computers, but the problem remains.

  I found a workaround by connection of bar codes in a USB hub, and then plug the USB hub to the computer.  And leave the USB - hub to take care of the communication with the Barcode Scanner.

  in this case, it takes about 2 seconds for the code scanner barcode to mount correctly in windows under the heading "devices and printers" and then works perfectly, even after a reboot.

  I googled after a response after my problem, but it seems I'm the only one who experience this issue. ?!

  Bought more than 40 computers that I have this problem.

  These were bought at different times with two different for suppliers

  Computer model are the following

  HP ProDesk 1 400 P/N5S21EA

  Specifikations:

  http://WWW8.HP.com/emea_africa/en/products/desktops/product-detail.html?OID=6614160#! tab = specifications

  Does anyone have an idea what could be wrong and how to fix it?

  Thanks in advance

  Hello

  The problem is not power - related.

  We use passive USB hubs that solves the problemon these computers.

  (it also works with the docks, or if you EliteDisplay E241 HP as we thers a usb hub 2 ports inbulit in monitor that works.)

  The problem lies in the incompatibility between the Intel USB controller and the hand scanner, can be connected to USB 3.0

  When you let another usb-controller support in handshakeing (such as a usb hub), it works.

  Datalogic or Intel would like to acknowledge this error.

  Because none of the big companies want to acknowledge the problem or repair, personally chose to switch to an AMD platform / CPU instead of the Intel and now it works fine!

  We get more performance for your money when AMD is usually less expensive to purchase.

  And because of the poor of Datalogic press where they don't even answer e-mail (their only channel for support)

  I chose to stop using their products. I'm going to use another provider / brand of barcodescanners.
