U r right!!we did not create a meta package for this device (because no one of the developers has this type of device, so we do not know which frontends / firmwares are needed to make it work).
But, all necessary drivers are in the feed.
Start with kernel-module-dvb-usb-af9035, and see what other modules (or firmware) it needs.
dmesg will tell you, when you plug the device.
(btw, your dmesg output is not complete, the interesting messages should follow just after the piece you've copied here)
This is the missed file I've just found on the web: dvb-usb-af9035-02.fw!
Now my USB DTT pen works at last!!
Thx a lot to all!!!
