It was a module and i put the option i /etc/modprobe.d/options next to options dvb-usb-dib0700 force_lna_activation=1 Running now, will be back with the results. On a side note: Could that be the reason debug=15 also might work as a workaround, there is so much traffic that the usb never suspends ? Thanks Phil for the "fix", hope it stays stable.. _______________________________________________ linux-dvb mailing list linux-dvb@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
