• R31 - unknown device problem

  I did a reinstall of Windows XP on my A31 and everything is fine, except for a problem of "unknown device" in Device Manager. The information shows that the unknown device on Intel 82801 CAM LPC Interface Controller - 248 C.

  In the past, I used a Thinkvantage system update utility to easily identify driver problems, but apparently, Lenovo saw fit to put an end to this tool.

  I've updated the BIOS, installed utilities from Intel chipset that I could find in the drivers/download section of the Lenovo support site - nothing did the trick so far.

  Overall, I'm looking in vain to understand what is involved. Also, the infrared driver seems to be part of this interface controller, but is shown as having no problem driver and working properly.

  Thoughts?

  OK, so maybe it wasn't the most scientific way to solve the problem, but it worked. I continued working through more all the drivers that I could possibly Lenovo download and kept pointing to different folders through the interface to 'update driver' in Device Manager. Finally, we found something he liked, which indicated "Thinkpad PM device.

  Don't know if this will help anyone else having this problem, but there is to go.

  Thank you!!

• Unknown device: Windows has stopped this device because it has reported problems (Code 43).

  I have Windows 7 Ultimate. Recently an unknown device keeps popping up in the device manager every time that I start to win. It is reported the location is in the front USB hub, but I haven't changed it anything lately. The device status says "Windows has stopped this device because it has reported problems (Code 43)". I can uninstall or disable it but it will get picked up again the next time that I reboot. All other usb devices (mouse, keyboard, webcam, UPS APC, external hard drive, printer) work very well. How can I get rid of this nuisance so that it is not reappear?

  If the problem coincided with connecting the inverter APC that may indicate the problem is with the inverter.

  Somewhat similar situation discussed in the following link:

  http://www.velocityreviews.com/forums/t527369-APC-ups-USB-as-unknown-device.html

  Your situation sounds similar as "Information system" leading the 'problem of the device' has an error Code "this device is working properly" but still "unknown device".

  I would say to detach from the APC UPS of the computer and uninstall any software related.

  Restart the computer and see if the "Unknown device" problem resolves.

• New x120e - "Unknown device" under USB controllers

  OK, so I'll try again from Firefox this time.

  For the first time poster, so please, be gentle. I recently ordered and received a x120e. The first time startup in Windows, the ThinkVantage Toolbox had a yellow exclamation point. To study more, I determined that it was due to an "unknown device" listed in the Windows Device Manager under USB controllers.

  I installed all the Windows updates available, and unknown device problem. When you open the device in Device Manager, the Statute indicates that "Windows has stopped this device because it has reported problems. (Code 43) ». The associated driver is usbfilter.sys, and if I try to update, it tells me that my current driver file is already up-to-date.

  If anyone can help with this question? I'd appreciate it - nothing worse than making a brand new machine with a hardware problem!

  Thank you

• Portege M440 - Vista problems: problems of Bluetooth, the unknown device and tablet.

  I just installed Vista on my Portege M400 and installed all the drivers on the driver Vista page.
  But I have several questions...

  1: bluetooth does not work. I can't find anywhere in Control Panel whatever it is on a connection bluetooth or something else.

  2: after you have installed all the drivers on the driver Vista page, there is 2 "unknown device" in Device Manager. I can't find any information on what are these devices. However, when I tried to manually install the driver bluetooth on the first of them "Unknown device" he admitted the driver. This does not work on the other. And it does not solve the problem of the bluetooth missing.

  3: the tablet itself feature works very well - the pen and everything. But when I turn the screen into tablet mode it does not change the screen layout. Or the buttons on the lower part of the screen to work.

  I hope that there is some sort of solution to these problems - and that someone can help me.

  I am also very interested in these drivers because all I know Toshiba Vista drivers are not available at this time.

• "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.

• 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.

• Problem with the unknown device - Code 43

  This USB controller has no drivers. It indicates the Version of the driver is 6.1.760.17586.

  I tried to disable and uninstall it with other USB controllers, but he returned as a unknown device vacuum.  This means that I can not connect devices to ports 3 & 4.  I am using Windows 7 32 bit.

  I'll be grateful for any advice.

  Thank you

  This means that the other usb ports on the PC work, if so it looks more like a problem of internal connection with these two ports

• HP Elitebook 8570W: driver problem: other devices - device base system and unknown device.

  Hi guys,.

  After doing a clean update on my HP elitebook 8570W I had a few unknown devices in my device manager.

  The first is a device called "base system" in PCI Slot 2 (bus PCI 36, device 0, function 1). I tried everything in my ability to determine what is this device and what drivers to install, so far without success.

  In the same section. other devices, there is another unknown device on PCI Express Root complex that gives me the same headache.

  I hope you guys can help me understand this.

  If you need further information, I will be happy to provide that.

  Kind regards

  Didier

  The base system device is certainly the JMicron card reader needs the driver, not the alcor one.

  If the driver above does not installing it automatically, try to install manually.

  To manually install the driver, go to Device Manager, click the Base system device.

  Click the driver tab.  Click on set to update driver.   Select her browse my computer for driver software option and find the folder of the driver that was created when you ran the file.

  The file is located in C:\SWSetup\sp63637

  Make sure that the include subfolders is selected and see the driver installs like that.
