Drivers are available in the kernel and the firmware is up to date. The kernel seems to detect and initialise it correctly and I get a message in the plex log about detecting it but not supported (this is a tuner for Australian TV networks)
Any hope of this tuner being supported in the future or do I just drop in the drawer full of unsupported USB tuners and wireless devices and buy yet another one… 
thanks
