Using adb directly runs it under your user, which will probably be unable to access the necessary USB device.
Starting the server manually under a privileged user is the easiest way to circumvent those restrictions if you don't want to fiddle with udev rules, which is the recommended solution, but is more work.

Thank you! Will keep it in mind! I have higher hopes now.
