It is QT1010 tuner driver issue. None is working for that currently or in near future. Feel free to fix :]


The wiki appears to show this stick as working. <http://linuxtv.org/wiki/index.php/Afatech_AF9015>.

Is this information incorrect or is it hit and miss depending on the host system?

Thanks,
David

I've a cheap USB DVB key that won't work with Kaffeine.
It identifies itself as KWorld USB DVB-T TV Stick II (VS-DVB-T 395U).
It shows up on Kaffeine's "Configure Television" dialog,
but scanning for channels finds nothing,
and tuning using an old channel list gives "Sorry - no available device found"

I had Kaffeine working OK with a different USB TV key.

dvbscan produces "WARNING:>>>  tuning failed!!!" messages.

The key works on XP using KWorld's HyperMedia Center.
Rebooting from there to Linux with warm USB key shows it contains 4.95.0
firmware.
At one point, such a warm reboot enabled Kaffeine to show TV.
That was with one of the early KDE4 Kaffeine candidates,
and an older linux kernel (sorry, I forget which).

Now using kernel modules in Linux version 2.6.34-gentoo-r6.
Kaffeine 1.0, KDE 4.4.5.  linuxtv-dvb-apps 1.1.1.20080317
on an ASUS EeePC 1000HE (Intel Atom processor).
