PCTV 461E Not being recognised by TVHeadend

I have just bought a PCTV 461E S2 tuner to run on my Pi 3+ running OSMC Kodi 18.2 RC1 and TVHeadend 4.2.6.

When I run lsusb I can see that the tuner is recognised by the Pi

osmc@osmc-server:~$ lsusb

but TVHeadend is not showing any tuners. I have checked that the firmware, dvb-demod-m88ds3103.fw is present in /lib/firmware

Has anyone managed to get this tuner working with OSMC and if so please can you let me know what I am missing.
Thanks
