Kimmo Satta, the hint with reconnecting the modem a few times does the trick! Thanks a lot! Basing on this and Hugues Fournier suggestion that this is a race conditions I tried removing the usb_storage module before pluging the modem and it works every time! I do this like this: sudo modprobe -r usb_storage
