RPi3 and TNT Avermedia Green HD Problem

Hi !
I’m a new user with a raspberry pi 3b and I’ve a problem with my tnt usb stick. It’s an Avermedia Volar Green HD
lsusb says :
Bus 001 Device 004: ID 07ca:3835 AVerMedia Technologies, Inc. AVerTV Volar Green HD (A835B)
I’ve downloaded the driver for this (https://github.com/OpenELEC/dvb-firmware/raw/master/firmware/dvb-usb-it9135-02.fw)
And put it in the /lib/firmware.
On each reboot unfortunately, the driver failed to load :
dvb_usb_af9035: probe of 1-1.5:1.0 failed with error -110
if i unplug and plug the stick, the key is recognized. But i need to restart tvheadend to see it and unfortunately again it detect no service.

I’ve tried the same thing on a raspbian, and all is working perfectly at boot :
[ 5.700762] usb 1-1.5: dvb_usb_af9035: prechip_version=83 chip_version=02 chip_type=9135

and tvheadend detect all the tv channels.
