Tvheadend

hi all,
i bought a t230c dvb-t2 adapter and i cant make it working.
i was trying 2 different OS.
tvheadend recognize the adapter, everything looks ok.
when im trying to scan im getting: failed.
on windows machine with the supplied software it is working, so its not hardware problem.
dmesg:
