Hi,
    I'm trying to make this device work. I've been unable to determine from
wiki if this device is really supported or not, although I'm afraid is not,
but probably not much effort is needed to support it. I say this because the
device is indeed detected and initialized when using up-to-date HG drivers,
but scanning for channels seems apparently fails althogh the device is
apparently tunning fine.

The device is identified by USB ids 2304:0228.


Here's the relevant dmesg output for this device:

Note that this device is a USB key containing both 1GB of memory (since the
USB storage messages shown) and the DVB-T adapter itself. The device seems
to be based on same DIBComm 7000PC device, apparentlyt handled by
dvb_usb_dib0700 driver (in dmesg you can see how 1.10 firmware file is
loaded for it). The frontend is created succesfully, so.


However, when trying to scan channels I get the following result:

So, as you can see the device is apparently tunning fine, but no channels
are detected. Note that this system has also a Nova-T 500 installed that
detects perfectly all available channels, so it's not an antenna problem.
Also, if I remove the antenna then I get (as expected) the usual "tunning
failed" messages, as the card is not able to lock on the signal then.
