No recognition of the dvb t tuner

hardware : Raspberry pi3
Tuner Avermedia Volar HD835 USB
I am using the latest osmc and seemed to work fine but nearly a month ago the tvheadend stopped suddenly.
As I looked in the web log , it seems that the usb tuner doesnt appear .
All the cables are ok, I installed for test the LibreElec and it is working .
Should I wait for kodi 17 some more days to solve the situation ?
