Thank you for your tipps! Uname -r gives a 3.13.0-57 generic Kernel
Rmmod hackrf gives me: "module hackrf is not currently loaded" I can't find powernap, so i guess it is not installed and the same with laptop-mode But: your tipps lead me to the tlp service. And there is an auto suspension for usb activated. So i deactivated it in /etc/default/tlp , or better added the device identifier to the blacklist and it now works like a charm!
