No more trouble with TVHeadend on Raspberry Pi 2 to run PCTV tripleStick 292e

Hi,

I'm new in this forum, so perhaps my question might sound L-driver like. But I have done a lot searching tutorials, blogs and forum threads without success..

I have installed HTS Tvheadend 4.0.8~jessie on a Raspberry Pi 2 under OSMC
(Linux version 4.3.3-3-osmc (root@vero) (gcc version 4.9.2 (Debian 4.9.2-10) ) #1 SMP PREEMPT Sat Jan 2 04:01:24 UTC 2016)

Everything is updated and upgraded. Installation went quite well. TVHeadend is running and can be accessed via <Raspi IP address>:9981, so configuration is possible.

A DBV adapter type PCTV tripleStick 292e is connected via an active USB hub. The stick seems to work, as the blue light is on. The Firmware dvb-demod-si2168-01.fw has been copied to /lib/Firmware.

Both adapters (DVB-C and DVB-T) are showing up in the configuration. A Network "Kabel" has been defined with Pre-defined Muxes "Germany: de-Kabel_Deutschland-Hannover". As a result 27 muxes are showing up. So far - so good.

But when the scan begins there are only error messages "*scan no data, failed*". All muxes stay in Scan Status IDLE and Scan Result FAIL.

The same happens when I connect an antenna instead of the cable and configure the DVB-T adapter with Network and muxes.

The stick itself is OK. I installed it with a Windows PC and the PCTV Software TVcenter**. Everything works well with either DVB-C or DVB-T.

So there is something between TVHeadend and the 292e not working well, but I have no idea what?

Any help or idea highly appreciated
Bernd
