I have flashed to the emmc of my Raspy Pi CM4 the Rasp.-OS, it boots up and I can see the desktop image. By default the USB Ports seem to be disabled (Energy saving, not good decision IMO) and ssh is as I know also disabled by default.

And: The Pi is not displayed as a external drive if I set the jumper to "disable emmc boot" and plug it via usb cable to my laptop...

What can I do to get the USB Ports activated?

I have found some tutorials about it but it didnt helped me further..

  • useful information would be what carrier board are you using
