If you have a patch to test, shout loudly.
Looks like the same bug:
AVerMedia HD Volar (A867) - Afatech AF9033
http://forum.sifteam.eu/sifbox-by-sif-team/125122-kernel-3-19-a867-xgaz-dove.html
http://git.linuxtv.org/cgit.cgi/media_build.git - no positive effect.
Ho ho ho
It seems the 'lsdvb' is what made the device unusable after re/boot.
Of course this applies to kernel >= 3.19.x
The device has to be unplugged and after a minute or two plugged back to be usable again.

Furthermore, it is sufficient to re/boot to the latest kernels,
and the device is K.O. again,
e.g.
# modinfo -n mxl5007t
/lib/modules/4.1.0-0.rc3.git0.1.fc23.x86_64+debug/kernel/drivers/media/tuners/mxl5007t.ko.xz

Keep in mind, this time it has nothing to do with 'lsdvb',
# lsdvb
-bash: /bin/lsdvb: Permission denied
It is that commit which causes the problem:
commit fe4860af002a4516dd878f7297b61e186c475b35
[media] [PATH,1/2] mxl5007 move reset to attach
... but I am pretty sure actual root of cause something else. Likely
your second tuner chip is on reset/powered off and due to that it does
not answer. I have almost similar device which works (DigitalNow TinyTwin).
Maybe I should try to test which are that tuner GPIO reset lines... but
I am a bit lazy :/
