Windows 7, error 43, USB and/or webcam not recognized

[Linoo]

Hello friends,
I recently installed Windows 7 in my ASUS M51A-f1 laptop. It works properly for some weeks. After some time my USB mouse and my laptop's inbuilt webcam does not working. I am getting unknown device error 43 in one of the USB hubs. I don't know why this is happening. I don't know why Windows 7 gives error 43 and USB and/or webcam nor recognized? Please help me to fix this problem.
Thank you.

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

If you get above error then you have to use following solution.
I think one of the drivers controlling the device notified the operating system that the device failed in some manner. In this case you have to run the Troubleshooting Wizard to fix this problem.

Hey I think you have to use Intel system drivers and other hardware drivers for your laptop to get rid out of this problem. This is because Asus does not have proper drivers for Windows 7 on their official site. In this case you have to go to the Intel website and from there you have to download driver for your computer.

Use following steps to fix this problem.
first disconnect all USB devices from your computer -> Now click on the "Start" button -> now go to search option and type "devmgmt.msc" and press enter -> Now your Device Manager window will open -> Now select "Universal Serial Bus controllers" -> now right click and press "Uninstall" and click "OK".
After that restart your computer. Now your windows 7 will automatically reinstall all USB controllers.

From your information it seems that it is some river related issue. Your computer's USB and webcam's driver does not install properly or it may get corrupted and that's why you are getting such type of problem. In this case you can use either of following two options.
1.Reinstall all your laptop's driver.
2.Upgrade your driver.
