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?

    Type Device Manager in the Search box above the Start button and press ENTER. Locate and right click on the device and click on Uninstall in the drop down list. Restart your computer. Does it reappear in Device Manager?

    Are there any yellow question marks in Device Manager? If yes what is the Device Error code.
