I'm reasonably sure that I had done these things.
I believe the TBS 6891 uses the cx23885 chipset/firmware, not the cx24117.

The files 'v4l-cx23885-avcore-01.fw' and 'v4l-cx23885-enc.fw' were 
already in /lib/firmware (from the 12.04 installation using the TBS 
drivers) and I copied '|dvb-fe-cx24117.fw|' to /lib/firmware having 
followed the instructions at 
https://github.com/ljalves/linux_media/wiki/CX24117-firmware.

Is there more to installing the firmware than just 'sudo cp 
v4l-cx23885-avcore-01.fw/lib/firmware'?

I will try again (though not until next weekend)

Thanks for the advice,

Gavin
