I have used mine successfully with a laptop with the 'buntu PPA build of 
0.28 for 14.04, last run a few weeks ago.  I think I used it with 16.04 
too, but don't have that box to hand.

It doesn't work with the el6 stock kernel, and the BZ above related to 
problems some time ago with the elrepo kernel build for el6 which, 
updated, still worked last month.

And I've just tried it with fc23, kernel 4.5.7-200.fc23 and a build 
based on rpmfusion 0.28-3.  As usual it took several runs to get a full 
set of good transports but I think I have that now.

I usually specify TV Standard DVB, the frequency of the BBC One HD Mux, 
8 MB BW, QAM-256, System DVB-T2, and scan all known muxes, with 
inter-mux links enabled. Then check (UK sense) and repeat.  In my case I 
often have to specify the BBC FOUR HD mux too.  I forget whether the 
DVB-T2 entry got into 0.27

But your ioctl error does hint at a kernel (or maybe connector) problem, 
as Stephen suggested.

I don't recollect seeing the 'adapterhd1' label before.  Did you use 
that when you tried your scan ?

... and it might be worth saying that master has very recent 
work-in-progress updates of the scheduler and tuner logic, although I 
don't know how these progress through the deb system.

Good luck.
