MyGica T230A doesn't work with DVB-C #246

I managed to build the modules on a slightly modified version of this package: https://aur.archlinux.org/packages/t230c2-git

And it does work using DVB-T (can't test DVB-T2 or ATSC).

However, when I plug in my cable, and run w_scan2 -fc -c HU, I have the following on many channels:

    signal ok:    QAM_AUTO f = 474000 kHz S6875C999  (0:0:0)
    Info: no data from PAT after 2 seconds
    deleting (QAM_AUTO f = 474000 kHz S6875C999  (0:0:0))

There's a small chance that the issue is caused by long usb cables - It's not easy to wire cable to my desktop. However, I used the same cable length when tested with DVB-T (DVB-C is QAM256, 6900 srate here)

Kernel is 5.12.0-1-MANJARO. Firmwares:

What did I do wrong? If I missed some vital information from the issue, I'm happy to add it.

TBS is not the manufacturer of your T230A, so @crazycat69 asked you to address your request to MyGica.
