Unknown Device - USB error Code 43

Anonymous

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?

    I have the same errors with my USB.

    I made sure all my windows updates are current.

    I've tried to update drivers, with the same errors.

    My USB reads:

    Hardware Ids:

    USB\UNKNOWN

    I've tried uninstalling all USB RootHubs and draining the power.

    I installed the Windows 7 64-bit HotFix posted. Rebooted.

    Still no fix!

    Hey guys, I just spent two weeks with the annoying USB connected error, accompanied by a ghost USB device in Device Manager that would just not go away. I tried registry hacks, uninstalling/updating/disabling the drivers etc. I didn't go as far as reformatting or re-installing Windows because from what I read that never seemed to help. Also unplugging my computer and letting it drain of power didn't fix the issue either. 

    What DID solve my USB woes was the Windows 7 "HotFix". It's basically a hotfix for USB problems on W7. It's litterally the only thing that fixed this issue- so if you've got this problem look no further.

    You can download the (x64) HotFix here:

    http://thehotfixshare.net/board/index.php?showtopic=17961

    I'm sure the hotfix is available for x32 as well. The name of the hotfix is "Windows6.1-KB2528984-v2-x64" if you need to further search it.

    Hope it helps!

    There is a simple and easy solution for this conflict no matter which device is giving you the problem or if is even all devices including Microsoft ones.

     

    Steps:

     

    Start

    Upper left hand corner click on Device Manager

    New window will open of Device Manager

    Next select USB Root Hub

    Right click on it and click Uninstall

    Do that for all the USB Root Hub that are there

     

    After they are all uninstalled, shut down your computer completely.  Pull out power cord and if it has a battery then remove it.  Press the Power button for a few seconds to drain any power left in the system.  Wait 5 minutes and reinstall the battery, Plug in the Power cord and restart the computer.

     

    Once you get full boot, go to www.microsoft .com and select downloads and then select Microsoft Update.  Minimise the page.

    Next plug in your USB device and let Windows download the drivers automatically for the device.  It should work fine.
