Hi
Well, I went to Aldi and bought one of these :-) :
http://aldi.dk/OFFER_DK_MI/OFFER_48/OFF07.SHTML , AGK 10508 DVB T/C USB tuner.
First thing to try was to see what /var/log/messages said:
Dec 1 09:33:51 xyz-desktop kernel: [25214.399750] usb 2-1.7: new high speed USB device using ehci_hcd and address 7
, which wasn't much (calling dmesg shows the same). So I tried with lsusb which gave the following:

and lsusb -t shows:

, where device 7 manifests it self twice.
As you can see there is a new device ID 1d19:8202 Dexatek Technology Ltd.
Dexatek has a web site and it seems they make other tv dongles.
However the Realtek IC seems to be new: RTL2841UHIDIR
When searching google for RTL2841 no clear result shows up. So I guess we are talking about some new chip from Realtek. So until now it is a brick on my pc.
I will try to see what I can manage to find out when I plug it into a windows pc.
I can see that some earlier dongle that Aldi has been selling also had some Dexatek usb id - here from linuxin.dk :

, here they try to get RTL2832U into work.
