That is to be expected, the device provides its own (patched?) firmware. This output is very
similar to what I have and it works fine. Tested reception on both DVB-T standards with
kaffeine, mumudvb2 tip and t2scan. You'll see the second part of dmesg message each time
You'll switch the channel or start tuning.

What differentiates between Your configuration and mine is I tested the stick in USB 2.0
port. Also what I'm missing from Your log is loading of dvb-demod-si2168-02.fw, I assume
it's present, since the driver doesn't complain.
I don't know if it's enough of a hint, since I'm not 100% sure if my TerraTec TC2 Stick is
exactly the same as VG0022A, but hope it helps
