I have the TBS-5990 working fine on one interface only. Both DVB Adapters register successfully, however only the first interface works.
I am using the media_build-0119.tar.bz2
It is running a Raspbian image. I have disabled the audio and i2c from the device tree boot up. Both interface work fine because if I swap the cables over I still get the same result.
uname -a
Linux raspberrypi 4.4.50-v7+ #970 SMP Mon Feb 20 19:18:29 GMT 2017 armv7l GNU/Linux
Any suggestions would be appreciated.
Regards
