Hi, I'm new to all this DVB thing, so please be nice :)
I bought one of these real cheap USB DVB-T sticks on ebay and thought it
was a Yakumo pen. However it turned out that they sent me an afatech
chipset no name stick. I found several pictures:
http://www.bttv-gallery.de/ search for Afatech DVB-T USB Dongle
and http://www.allnet.de/product_info_allnet.php?cPath=_&products_id=99975*
*So i followed all the instructions about afatech. I'm using ubuntu 7.04
Feisty Fawn. i copied the firmware and did install all the software.
i show you now what lsusb -v says:

Here's what happens when i plug it into my USB Slot and read dmesg:

after a while it also shows this line: Quantek QT1010 successfully

but i cant really tell you after what time it shows this.
scan -n -o zap -p

So do you need any additional information ? i tried to privide you with
the information which i gues sis the important one.
Thanks for your help.
Ps.: the vendor offered me to send it back and get an afatech af9015
instead ?? is this one better supported ? i read its driver is not
finished yet.
Cheers Daniel
