Tvheadend

Hello,

After migrating from a old QNAP to a TS-251D, I'm strugging to make TVheadend works again. Any help is more than welcome.

I have a Sundtek USB tunner installed with the QPKG firmware (TVH_Dev_Sundtek_0.7.4.qpkg) and TVheadend installed also from the latest QPKG (TVHeadend_0.9.8.1_x86_64.qpkg)

Using mediaclient, if I scan with the correct parameters (according to my TV provider) I get full signal

 /usr/bin/mediaclient -m DVBC -f 306000000 -M QAM64 -S 6900000
 /usr/bin/mediaclient --readsignal=0  -d /dev/dvb/adapter0/frontend0

SIGNAL: [.................................] (100%) BER:      0 FREQ: 306000000  Hz LOCKED: YES MER: 364 SYM: 6900000 MOD: QAM64
SIGNAL: [.................................] (100%) BER:      0 FREQ: 306000000  Hz LOCKED: YES MER: 362 SYM: 6900000 MOD: QAM64
SIGNAL: [.................................] (100%) BER:      0 FREQ: 306000000  Hz LOCKED: YES MER: 363 SYM: 6900000 MOD: QAM64
SIGNAL: [.................................] (100%) BER:      0 FREQ: 306000000  Hz LOCKED: YES MER: 362 SYM: 6900000 MOD: QAM64

In Tvheadend I see my USB device but when I try to scan for channels I got the following error in the logs:
