Diagnose the Problem
1. Determine whether the problem is not due to a malfunction of the USB device itself, but rather of the computer itself. To do this, plug the USB device into another computer. If the device does not work, then the problem is most likely coming from the device itself. If the USB device does work, then you know the problem is coming from the computer, and you can use the steps below to fix it.
2. Check to see whether or not the USB is correctly configured for the peripheral device that you are using it for. This peripheral may be a digital camera, scanner, PSP or camcorder that you are trying to connect to the PC with via the USB. Use the product manual to check if the USB cable matches the speed of the device. This is important because USB 2.0 cables may not work with USB 1.1 configured devices and vice versa.

3. Double-check to see that the cable corresponds with the type of device. If not, you will need to connect the device with the proper USB cable.
4. Continue to Section #2 below if you still receive 'Error Code 10' even after switching cables.
Use Your Device Manager to Locate the Problem
