What is ERROR CODE 43? 
Microsoft describe that this error happen because "One of the drivers controlling the device notified the operating system that the device failed in some manner. "
There are several way to solve this problem, and from my opinion this happen basically cause by the SOFTWARE or the HARDWARE. There is no specific reason why this happen, a mystery that cause us a headache to figure what cause this error.

What Causing This Error? 
Theoretically, from the solution we may guess what the causes, such as dusty hardware, electrical overcharge on the component, faulty hardware or corrupted Windows file. This may happen on both the external or Internal hardware which is based on USB type hardware, such as Pendrive (USB storage), Card reader, USB Mouse and Keyboard, Webcam etc and it can happen on all windows operating system.
