I bought a PCTV DVB-S2 Stick (461e) because it was on the supported list on linuxtv.org (http://www.linuxtv.org/wiki/index.php/Pinnacle_PCTV_DVB-S2_Stick_(461e) )

However when I inserted it into my mediaserver with kaffeine it did not find any channels. Only once it looked like it got some signal.

Trying to attach a satellite finder indicated that no power was put on the cable for the LNB. Trying to insert the stick into a Windows 8 machine and installing the PCTV software, proved that the stick indeed did feed the LNB with power.

Next I tried to insert the stick to my laptop, with the satellite finder too. When running scandvb the sattelite finder went active for a few seconds, and the got silent. Rerunning scandvb gave no response. But removing the stick and reinserting it would repeat this when running scandvb.

This leaves me to suspect that the stick is reset during the scan.
Im running a Fedora 20 with Linux 3.17.7-200.fc20.x86_64

When inserting I get these messages in /var/log/messages

I also tried to remove the firmware file, in which case to activity was registered on the satellite finder. And when putting it back I could repeat the activity without unmounting it first.

Anyone have some good ideas
