Hi. I assembled my MMU2 and COM port is not found.
ATm32U4DFU driver was not found.
I did all that I can do, to fix this MMU2. Grounding strap for any Electric static, was used as a precaution. MK3 says, MMU2 = N/A.
None of the lights, light up.
Neither motor movements. By hand, all motors turn freely.
I did all the checks and rechecked many times.
What issue do I have???
