Yes, Windows sees “RAMPS (COM6)” without the shield connected. With RAMPS shield on, no power plugged into the ramps shield, Windows sees RAMPS (COM6).

I have loaded and started Pronterface , plugged in the power supply to RAMPs (USB connected). I selected COM6 @ 250000 and I get this error message “ValueError: Cannot configure port, some setting was wrong. Original message: [Error 31] A device attached to the system is not functioning.”
Here is the entire text:

When I connect my other Mega to the RAMPS shield, plug the USB and Power the RAMPs board, change the COM port, it connects and drives the stepper connected.

Here it the text:
