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

I have Windows 7 Ultimate. Since very recently an unknown device keeps popping up in the device manager every time I start Win. It's reported location is within the front USB root hub but I haven't changed there anything lately. The device status reports "Windows has stopped this device because it has reported problems (Code 43)". I can uninstall/disable it but it will get picked up again the next time I reboot. All other usb devices (mouse, keyboard, web camera, APC UPS, external drive, printer) work fine. How do I get rid of this nuisance so that it doesn't reappear?

If the problem coincided with hooking up the APC UPS that may indicate the problem is with the UPS.

Somewhat similar situation discussed in the following link:

Your situations seems similar as from the "System Information" file the "problem device" has an Error Code "This device is working properly" yet remains an "Unknown Device".

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

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

    I replaced my USB device with a Belkin lead and the problem was rectified straightaway, The device I had been using was a cheaper  version but as soon as I used the Belkin USB lead to link my computer to my printer the error 43 code did not appear, the device was recognised and I am now using my HP printer successfully
