• "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.

• 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.

• Windows XP SP3 USB errors / unknown devices with Plug and Play

  I have problems with USB flash drives and other plug-and-play devices detected by windows. 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. After Googling my eyeballs, I gave up and need help please. The only thing I can do now is to reinstall the operating system that really, really, I don't want to do.

  UPDATE *.

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

• 802.11 wireless pen drive recognized as 'unknown device' under USB. Help, please.

  Specs: Windows XP Home Edition version 2002, Service Pack 2. This is the version of XP OEM. Processor Intel pentium 4 2.00 GHz. 1.50 GB of ram.

  After an unknown incident (i suspect headphones usb), my wireless USB key has ceased to be recognized as such and become everything simply an "unknown device" under "USB bus controllers. Although windows tells me there is no drivers for the device installed, the wireless pen drive is signed with the Publisher of Microsoft Windows with a version of driver 5.1.2600.0, Microsoft being the driver provider.

  Compound number, the 802.11 device is listed under "Other devices" when 'show hidden devices' is selected and the variable "devmgr_show_nonpresent_devices" entered "environment variables", but is washed out-showing that the system thinks that the device is not currently connected to the computer. In addition, under details, it displays error code 45: the device is not connected to the computer. And it is. It's very hip. as cement and connected tape.

  I plugged the wireless key USB in all the usb ports on the computer, every time with her recognized as 'unknown device' under usb controllers. I entered in the safe mode, uninstalled all the usb controllers and root usb hub drivers and let windows the respawn after reboot in order to solve the problem. No dice.

  I also plugged the USB in a different desktop and it works like a charm, so the issue is not with the hardware.

  Clearly there that a conflict with drivers/registry/God knows what, but I'm at a loss. Somehow, windows has taken its decision and the player associated with "unknown device" and I see no way to make the system "forget" that the USB was never connected. How can I remove the ghost driver "unknown device" manually or force windows to re-associate the key wireless USB with "other devices" (with the yellow? mark) and not this useless usb driver "unknown device"?

  Thanks for the help!
