Failed to connect

Hi guys,

Never had this before. Built a dozen (same) printers.
Standard installation, Arduino Mega/RAMPS1.4. Nothing fancy.
Port is not seen in Arduino nor the slicer.
Already replaced both
When I disconnect Arduino from RAMPS I can connect to Arduino and upload firmware. Plug in RAMPS again, connection is gone.
Checked, rechecked all connections.
What's on the RAMPS : 2x TMC2100 for both X and Y the other drivers are standard.

I'm stuck here...confused smiley

meanwhile found the faulty component.
I systematically removed all connectors from RAMPS, still no connection.
What's left...? Yep drivers. Removing all drivers and the very last driver removed got me connected again.

It's always the last one, no matter what you're investigating...
