I have a Enter E-GPV gamepad that was working fine on my win 7 setup..however, it has now stopped working. The light on the gamepad does not turn on nor is it detected by windows in any way. Tried re-installing the drivers but in vain. Tried it in other ports and on a laptop..same result: no response. I have another enter E-GPV gamepad that works perfectly on both the systems. Is the gamepad spoilt ? What could be the cause and can it be repaired?
