• HP ProBook 4510 s with Webcam Windows7 (x 86) as "Unknown device" in Device Manager.

  Hello.

  Of my friends has a very specific problem with USB (unknown device). It is that we know exactly it is problem with the WEBCAM and we tried the update:

  -Drivers for intel chipset

  -Drivers for Webcam

  -Do you have Flash Bios

  -Firmware...

  You name it, we have installed.

  Thing is that HE WORKED for a time, but after a reboot, it was gone.

  I think the problem is somewhere in the registry, but I have no idea of what to look for.

  The device type: USB controller

  Standard USB host controller

  Port_ #0005.Hub_ #0004

  State: windows has stopped this device because it has reported problems. (code 43)

  Hardware ID: USB\UNKNOWN

  GUID: {36fc9e60-c465-11cf-8056-444553540000}

  Key: {36fc9e60-c465-11cf-8056-444553540000}-0016

  We tried a lot of things that I found on this forum, windows7 forums...

  This means that the greater likelihood is that he doesn't have the webcam.

  Best regards

  ERICO

• Satellite A200 - Webcam disconnected message 'unknown device '.

  My integrated webcam has stopped working. I downloaded and installed the latest driver available (Chicony 1.7.115.0213) but still does not work the camera. When I run the software assistant camera it tells me that the camera is disconnected. On the other hand, there is a notice from Windows telling me that there is an unknown USB device (Port_ #0001.Hub_ #0002) which I suppose is the camera. I tried Googling the issue or search in this forum but I have no answer. I would be really grateful if anyone can help me find a solution. Just in case, here is my PC details:

  Hello

  > On the other hand there is a notice from Windows telling me that there is an unknown USB device (Port_ #0001.Hub_ #0002) which I suppose is the camera

  Yes, it could be the internal webcam.
  Seems that the driver has not been installed correctly.
  What to say; first remove the old webcam software from the system.
  Then clean the operating system using a tool like CCLeaner, for example.
  After that, go into Device Manager and remove the unknown device.
  Restart the unit.
  Reinstall the webcam software and check if the device has been recognized again.

• "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

  Sincerely

  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.

• 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.

• Satellite A500 USB problem - unknown device.

  Hello

  Have a Satellite A500 I recently restored to factory from the recovery partition and reinstalled my Win7 upgrade.

  I have a couple of unknown devices in Device Manager and have no way of knowing what they are.
  They would normally be a problem for me except that I'm also the sounds of disconnecting USB every now and then and caveats relating to the devices being plugged into a port USB2 not high speed.

  I have of course plugged anything in time so I expect there is a device which is malfunctioning and not detected correctly.

  The devices I first suspected (webcam, TV Tuner, touchpad) all normally appear in Device Manager so I'm at a loss as to what is the cause.

  Any ideas?
  Beards

  Hello

  I understand this correctly?

  You restored the A500 to the factory settings using the Toshiba recovery procedure and the unknown devices still shows up in the Device Manager?

  That s strange because the recovery disk to put the laptop in the same State as on the first day of purchase. So generally unknown devices should not appear and all drivers must be installed correctly.

  However, I found an interesting and in my eyes useful HowTo document that should help you to know which drivers are missing in your case.

After taking all possible measures to correct this problem (e.g. windows update, chip / update of the bios, update driver, driver and media ultilites reinstall, uninstall and allow windows update after restarting, removal of hidden devices and even remote tech support from Dell) whenever I connect a flash drive or use all plug-and-play devices it is detected as an unknown device and I can not put updated pilot any port I use. Hardware problems were excluded dute to recognition of the device and USB keyboard and USB mouse are functioning properly. Also these same plug-and-play devices worked well on other items of work.

  UPDATE *.

  Dell has replaced the motherboard and the problem was solved. Thanks to all here who offered advice and patience.
