In the event that it works for HD with winderz but not linux, the list to ask next would be the v4l list on vger.kernel.org (I think, I've not been on it in a couple years) Some pretty sharp digital video folks hang out there. You'll need to show them the lspci or lsusb/lshw output so they can properly ID the chipset in the stick.

I can confirm that it works with Windows (same stick, on the same machine). There seem to be two problems:
a) Can Kaffeine display HD TV? If not there's not much to do short of looking for another program.
kaffeine can display HD TV, but I've had to move some firmware around so it could be found and uploaded to my card, and I can report that tv test utilities that are supplied by the pcHDTV-3000 card (that I have) vendor, now display all the local channels signal strengths with dtvscan, and that dtvsnr now reports sensible values on the active channels, and likewise dtvsignal shows sensible signal strengths on the locally active channels.
HOWEVER, kaffeine is not finding what dtvscan discovers, IMNSHO because it scans about 20x faster than the card can achieve lock on a new frequency, ignoring the 1.5 to 2 or even 5 seconds allowed for lock time in one of its setup menu's. kaffeine's scanner claims it has scanned half a gigahertz and found nothing in something under a minute. dtvscan takes around 3, maybe 4 minutes, starting at channel 2, to find and report good signals on north american atsc channels 5, 10, 12, and 33.
b) How can I create a new program list, as w_scan crashes (so badly that it locks the machine competely).
You may have something missplaced, before I could make the cards software/firmware load, I had to cp the contents of /usr/lib/hotplug/firmware/* to /lib/firmware. It seems todays systems have moved the default location for this stuff, which for my card, was set 9 years ago, in 2007. Along that same train of thought, perhaps something kaffeine needs has been moved. Its all stable here, no crashes while exploring the dvb menu's, but it doesn't work either. I see it has the ability to manually add a channel but haven't tried that, I should have at least one eye open, which this time of the night locally, isn't always the state. Theoretically, I should be able to use the data that dtvsignal reports to compose a manually added entry.
These utilities I mention are of course specific to this card, hopefully you have similar utilities available for your card or dongle?
So you may want to take a look at your dmesg output for messages similar to this:
[56092.124304] or51132: Waiting for firmware upload(dvb-fe-or51132-vsb.fw)... [56092.124323] cx88-mpeg driver manager 0000:01:08.2: firmware: failed to load dvb-fe-or51132-vsb.fw (-2) [56092.124327] cx88-mpeg driver manager 0000:01:08.2: Direct firmware load failed with error -2 [56092.124329] cx88-mpeg driver manager 0000:01:08.2: Falling back to user helper
Which should look more like this, card diffs notwithstanding:
[56620.469051] or51132: Waiting for firmware upload(dvb-fe-or51132-vsb.fw)... [56620.469454] cx88-mpeg driver manager 0000:01:08.2: firmware: direct-loading firmware dvb-fe-or51132-vsb.fw [56623.063706] or51132: Version: 10001134-19430000 (113-4-194-3) [56623.064325] or51132: Firmware upload complete.
And, noting the cx88 above, an "lsmod | grep cx88" returns quite a lengthy list of suspects:

I would assume that for whatever chipset is in your device, you would be getting a similar output as above, chipset diffs notwithsranding.
Maybe there is a clue here for you. For me, its plain that kaffeine itself isn't functional as currently configured on my machine, using the TDE version of 8.8.
I'll take a look at the v4l list. thanks.
