I have a similar problem - for some reason VDSB without a real explanation.

Hello All,
The issue was not related to USB whatsoever - my channels.conf was the issue.
I created it with "scan" from the dvb-utils package. Turns out that "scan -o vdr" outputs the channel frequency in kHz, where vdr expects it in Hz. Obviously, the vdr still tunes but the recording part is baffled.

This is weird. dvbdevice.c has the function FrequencyToHz that is used for DVB-T and DVB-C. That should make the conversion automatically.
