Answer 1

Hi Umesh,

Code 43 implies that Windows has stopped this device because it has reported problems.

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

Follow the steps listed below:

Step 1:

To resolve the problem, let's first open the Hardware and Devices troubleshooter to run the automated troubleshooting services.

Step 2:

If the troubleshooter does not fix the issue, let’s use Device Manager to disable and re-enable all the USB controllers. This lets the controllers recover the USB port from its unresponsive condition. The USB controllers represent the USB ports in Device Manager.

To disable and re-enable the USB controllers, follow these steps:

a.    Click Start, type device manager in the **** Start search box and hit Enter.

b.     ExpandUniversal Serial Bus controllers.

Note You might have to scroll down the list to find this item.

c.    Right-click the first USB controller under  Universal Serial Bus controllers, and then click Uninstall to remove it.

d.    Repeat the above step for each USB controller that is listed under  Universal Serial Bus controllers.

e.    Restart the computer. After the computer starts, Windows will automatically scan for hardware changes and reinstall all the USB controllers that you uninstalled.

f.    Check the USB device to see whether it is working.

Additionally, make sure you update the chipset drivers on your computer. Download and install the latest Windows 7 compatible drivers and check if that fixes the issue.

Hi Azeez, 

I tried ur suggestion of disable and re-enable the USB controllers, it didn't work. I also tried updating the drivers, it says I have the latest drivers. I even contacted the maker of the USB Bluetooth adapter I'm trying to install & got their latest drivers for the device. I tried installing it on 2 different OS (XP Pro & Windows 7) Nothing I do is working, what would make the USB port not recognize my adapter? Any advise would be appreciated, thanks.
