Hi all,

can you say what's the meaning of such a message?

I'm using it with:
dvbscan  /usr/share/dvb/dvb-t/it-MyCity
Unable to query frontend status

using a TerraTec Electronic GmbH with dvb-usb-dib0700 driver.

The module seems to be loaded correctly, indeed I get this in the
kernel log:

The led on the device switched on when I performed the first scan.

The device is reported to be supported on the DVB wiki:

Help or hints will be appreciated.

Regards.

I believe I have seen a message like this when something else
is talking to the card already. For instance, I run my cards in a Mythtv system, and in mythtv there is a setting to only attach to the card when actually using the card. If that setting is set incorrectly, mythtv will attach to the card at startup, and keep exclusive use of the card, not allowing
anyone else to access the card at all.
