Nevermind this for the time being...all is pointing to open-sasc-ng being
the culprit here...
Just to add a datapoint - I have the same problem: I can't seem to
successfully scan for channels. I've taken open-sasc-ng out of the
equation by simply not loading the loopback device and scan directly
on the true frontend.
These are my bits:

I have also tried the mantis module from v4l-dvb without success. The
card is then recognized as TDA10021 instead of TDA10023, just as you
describe.
Typically, I have to do "modprobe -r mantis;modprobe mantis" right
before I try to scan (with w_scan, scandvb og mythtv) in order to get
any channels at all. But the joy doesn't last for long, and I get
stuff like
kernel: mantis_ack_wait (0): Slave RACK Fail !
in /var/log/messages.
I guess the problems mentioned in the following post are related:

Hope we can find a solution to this!

I actually found what my problem was. It seems that open-sasc-ng has a
weird bug, which means you can't tell it to log to a logfile by using
the --log argument.
If I remove the '--log /var/log/open-sasc-ng.log' argument and instead
lets it log directly to syslog, it works fine. I'm using syslog-ng, so
it's not a problem directing all open-sasc-ng log traffic to a specific
logfile anyway.
