[mythtvnz] SkyStar 2 DVB-S card failing to load after 20.04 upgrade

[Wade Maxfield]

Hi All,

Ive just upgraded my Myth box from Ubuntu 16.04 to 20.04 (via do-release-upgrade) and have hit a few snags.
Machine has been running for a few years, so I’m a bit rusty on getting it back running properly.

First one I’m trying to tackle is one of my SkyStar 2 DVB-S cards isn’t being fully recognised.

It should appear as /dev/dvb/adaptor1 but doesn’t appear at all. adapter0 is a SkyStar 2, adapter 2&3 are a TBS DVB card

me$ ll /dev/dvb/
total 0
drwxr-xr-x 11 root root  220 Oct 17 19:54 .
drwxr-xr-x 23 root root 4.6K Oct 17 19:54 ..
drwxr-xr-x  2 root root  120 Oct 17 19:54 adapter0
drwxr-xr-x  2 root root  120 Oct 17 19:54 adapter2
drwxr-xr-x  2 root root  120 Oct 17 19:54 adapter3


me$ cat /etc/modprobe.d/dvb.conf
# Technisat SkySTAR2 DVB-S
options b2c2_flexcop_pci adapter_nr=0,1

#TBS 6909
options tbsecp3 adapter_nr=2,3


dmseg says no frontend driver found

It does exist as a pci device:

Note the second card has Kernel driver in use: b2c2_flexcop_pci, but the first card doesn’t.

Any tips or things I should be looking at?
