Unknown Device - USB error Code 43

Anonymous
2011-12-15T00:54:36+00:00

Dell XPS m1330 running Win7 Pro 32-bit, service pack 1.

I have had this problem seemingly forever but have been ignoring it, as it doesn't seem to affect the performance of my laptop, but now I'm wondering why it has happened.

I have 7 Intel ICH8 host controllers, a Microsoft Keyboard and Mouse driver, USB Composite Device, USB Mass Storage Device and 7 USB Root Hubs that all seem to work fine, I have no problems using any devices I plug in to the machine, but there is an Unknown Device, with no hardware/device details available, reporting a Code 43.

I have uninstalled and reinstalled all the USB drivers, didn't help, in fact it made it worse as it seems to have lost my fingerprint reader (the reader is installed but apparently not connected to anything). There are no new driver updates. I have no idea what the Unknown Device is referring to, other than Port#0002 Hub#0001.

As I said, all external USB ports work fine, and until I tried fixing it, the Fingerprint reader was fine as well, I don't know what else should be on USB, so don't know what to fix.

Any help?

    Hi,

    I would suggest you to try the following methods and check if it helps.

    Method 1:

    Run the fixit from the following Microsoft Fixit article and check if it helps.

    Hardware devices are not working or are not detected in Windows:

    http://support.microsoft.com/mats/hardware_device_problems/

    Method 2:

    Run the Hardware and Devices troubleshooter and check if it helps.

    Open the Hardware and Devices troubleshooter:

    http://windows.microsoft.com/en-us/windows7/Open-the-Hardware-and-Devices-troubleshooter

    And also try unplugging all USB devices one by one and check exactly which device is giving the error.

    Hope the information is helpful.

    Thanks for the reply.

    I have tried both the fixit and the troubleshooting methods, each time I get a report saying There is a problem with Unknown Device, and directs me to the properties dialog of the unknown USB device. 

    All of my external USB ports work fine, and I can't remove anything that might be on an internal USB device.

    In the Unknown Device Properties, I see the type is USB controllers, Port #0002, Hub #0001, status: Windows has stopped the device because it has reported problems (Code 43).

    Under Details, I see that the hardware Ids is USB/UNKNOWN. The Physical Device Object name is \Device\USBPDO-8. There is some information in the Driver Key, Bus type, etc etc, but it is all meaningless to me, and I don't know if any of it will help in a diagnosis.

    Thanks

    Hi,

    Recommended resolution for code 43:

    One of the drivers controlling the device notified the operating system that the device failed in some manner.

    If you have already run the Troubleshooting Wizard, you might want to check the hardware documentation for more information about diagnosing the problem.

    Hope the information is helpful.

    This did not answer my question. I still get the message, and I still don't know what is causing it. None of my USB devices are failing, all of my IO on the laptop are still fully functional, and in fact I get the message when there are no devices attached to USB.

    Given that you are just repeating the same answer (which I will allow should work for most cases, but as stated does not apply to mine), I'm guessing that means you don't know what to do about it either, so I will leave your answer marked as "answer" and abandon this thread.
