ERROR: Sorry - i couldn't get any working frequency/transponder
Nothing to scan!!

The device looks to me recognised and initialised but don't get w_scan
a channel list.

So what am I missing?

Thanks Frank

Get connected to a better antenna, or move the current one to a better
location? I presume you're somewhere where you'd expect to see
channels?

Try a different USB port; sounds odd, but I found a few RTL2832
`Nothing to scan' with Google where that helped.

stick works with my antenna on another Laptop with win7 :-(

I've tried all USB ports both on my laptop and docking station, with no
success.

Tried kaffein as well. It has a field where I assume theres's supposed
to be a bar showing the signal strength where I see nothing

I was looking for firmware but couldn't find. LinuxTV.org doesn't
mention any firmware either for this stick.

Did you try other software like tvheadend? Maybe it would help to
extract the firmware from a newer windows driver, but I had no luck yet
doing this.

I've extracted the most current Windows diver but to be honest don't
know what to look for since I don't know how the FW is called there.

I'm sending it back and have ordered a Hauppage WinTV which hopefully
better supported. At least there's reports of success on the local LUG
list.

I can confirm that the Hauppage WinTV solo works well with the
openelec-dvb-firmware package from AUR and VLC.
