HI,
I have a server with 5 TBS 6904 cards and one TBS 6205.
Ubuntu 18.04.2
4.15.0-51-generic
I just used the install.sh script. I had to fix an error in v4l ;
sudo nano netup_unidvb_i2c.c
( I added line :
int num=0;
This card is irrelevant to my TBS issue)
to make it compile.
The installation then went okay.
Now the problem is, I get only one shot tuning in the channel see below.
When I hit Ctrl-C and try the same command, it can't lock anymore.
This happens on every DVB-S tuner in the server.
After reboot it works again once.
This sounds like a bug in firmware / driver to me?

I also tried with mumudvb and it has the same issue.
There are no warnings in dmesg during these issues.
