Tvheadend

Hello!

I am having trouble with the MyGica "Mini DVB-(T/T2/C) USB Stick T230C Lite" and tvheadend on Raspberry Pi OS.
It is listed in the Adapters section and when using the wizard it finds 8 muxes. But during the Scan finds 0 services. And the Scan Status of the muxes is on IDLE.
My dmesg says something about invalid firmware. This is part of it:

This is the content of my firmware directory. I was under the impression I had downloaded the correct files:

pi@raspberrypi:~ $ ls /lib/firmware/*si*.fw -la

do you have any idea what can fix this issue?

Thank you!
