Hi all
In a fit of madness I decided to add more than 8 tuners to my TV Headend set-up. I hit the default kernel limit of 8 tuners max. Downloaded Media_Build, ran both kconfig (to allow me to alter the number of max tuners as a config option) and then also tried hard coding the media_build/linux/drivers/media/dvb-core/dvbdev.h to force 16 tuners. I ran make and then sudo make install, and I'm pretty certain my changes to dvbdev.h were included as I made a mistake with a comment that got flagged during make.
I have 3 x PS3 Play TV Dual DVB-T tuners (and all 6 adaptors have worked in a set-up before together) I have 3 x August T210v1 DVB-T2 tuners. Again they all work together in an 8 tuner or less set-up.
I still only see 7 or 8 adaptor max - depends on the order I plug them in.
When the final Play TV is the last one to be connected I get :

[ 19.402828] dvb-usb: Sony PlayTV error while loading driver (-23) seems to suggest that the final PS3 Play TV isn't correctly initialised.
lsusb -t seems to confirm this, as one of the three PS3 Play TV instances doesn't have a Driver loaded (Port 3: Dev 10 connected to Port 5: Dev 6 hub).

If I leave an August T210v1 to be the last to be plugged in I get the following :

Where you can see that there is a Driver-less instance at Port 2: Dev 10
And in dmesg

Any tips? Could it be that my new media_build hasn't 'taken'?
Any hints on how to proceed? Currently running Ubuntu 14.04.3 LTS with kernel 3.19.0-47-generic
