Reboot/Restart when connecting by USB to Raspberry Pi or PC on P3 Pro

Maranthalas

As soon as I connect my P3 by USB to Raspberry Pi or to my PC, directly or by hub, it will enter a reboot/restart cycle. I would guess it has somethimg to do witth the usb current on the usb connection.So it is not possible to connect to the printer. On Pronterface under windows 11 I only get "connection refused", Repetier server on the Raspberry Pi is not able to connect at all.
Any suggestions?

Tried different cables, raspberry pies and PCs, as well with and without a powered usb hub, under pronterface, octoprint and repetier server. As well with and without a covered 5v + pin on the usb cables.
Slightly different results from going into a restart cycle at once, to once in a while to connecting, and then restarting. It gets to recognizing the printer, to sending data and then restarting after the printer not responding. Very frustrating.
