Hi,

I having problems to get my DeLOCK DVB-T/DVB-C USB Receiver 61959 running.
I think that my DVB-C Stick is correctly installed, as on dmesg | grep DVB I get this:

[ 9.730751] em28xx: DVB interface 0 found: isoc
[ 13.260639] em2874 #0: MaxMedia UB425-TC/Delock 61959: only DVB-C supported by that driver version
[ 13.260674] DVB: registering new adapter (em2874 #0)
[ 13.260711] usb 1-1.2: DVB: registering adapter 0 frontend 0 (DRXK DVB-C DVB-T)...

The problem is, that at initscan I get the following:

2013-12-25 08:09:57.532 [ INFO] mpegts: 114000 - starting for 'initscan' (weight 2)

2013-12-25 08:10:02.007 [ INFO] subscription: "initscan" unsubscribing

This is my installed tvheadend version: HTS Tvheadend 3.9.304~gc50b049

Anyone know whats wrong?

Thank you
