My hardware: TP-Link Archer C5 with OpenWRT 14.07 Barrier Breaker Terratec HTC XS HD USB (http://www.terratec.net/details.php?artnr=Cinergy+HTC+USB+XS+HD) I built OpenWRT from source which worked fine. But now after inserting the kernel modules for the TV stick and the firmware, I can't get tvheadend to perform a scan and w_scan to find anything. First it threw the same error as you encountered (that's how I found you). Thanks to your trick the error is gone, but still no signal, it recognizes a valid mux at 121Mhz, but no channels. My dmesg looks good, just as on the Ubuntu machine where the stick works. I don't know the specifications (RF signal strength) of the stick, but it seems that it is a little bit vulnerable to signal errors. On the Ubuntu machine it sometimes has stuttering video for me. Have you found a solution to make the stick work? If you could share it that would be really great.
