Anywhereusb2 g2 blinks green-2red-3red-2red-green

What can I do when the anywhereusb2 g2 is only blinking green - 2x red - 3x red - 2x red - green over and over again? It has no network connectivity and the led is not lighting up when a usb stick is connected.
I already tried resetting the device but that didn´t work too.

This sounds like a defective device / bad hardware. You could open a support ticket with Digi and provide the serial number there, to see if it’s still covered under warranty or not.
