My setup is a HP i5 Compaq 8100 with a clean install of ISO Mythbuntu 64bit
0.28/16.04. The Linux Support provides a firmware IP address and suggests
the required driver will be included in kernel 4.8

I copied the firmware dvb-demod-si2168-b40-01.fw to /lib/firmware/ and
installed kernel 4.8 to get the required driver.

The Linux Support shows the lspci output to be as follows:

>
> lspci -v

"MythTV Backend Setup>Capture Cards>New Capture Card" took 5 minutes to
respond with [DVB: /dev/dvb/adapter0/frantend0 ].
Then later with "Input Connection>Scan for Channels>Scan Configuration"
showed error: Scan Type: "Failed to open card".

I need help to get this tuner working on Myth.

Thanks for your interest and thoughts?

Regards
Glen
