[linux-dvb] Yakumo QuickStick frontend tuning problem

[Frank Breitling]

Hello,

I have been trying to get a Yakumo QuickStick DVB-T (USB 2.0) running with kernel 2.6.13.2.
First I plugged in the stick and as the syslog shows (attached below) the stick is recognized although "recv bulk message failed: -110". Then I tried:

<
host:~$ dvbtune -f 1770000 
Using DVB card "WideView USB DVB-T"
tuning DVB-T (in United Kingdom) to 1770000 Hz
polling....
Getting frontend event
FE_STATUS:
polling....
Getting frontend event
FE_STATUS: FE_TIMEDOUT
Not able to lock to the signal on the given frequency
>

So there seems to be a tuning problem related to the frontend. As stated at
http://www.linuxtv.org/wiki/index.php/DVB_USB#WideView.2FYakumo.2FHama.2FTyphoon.2FYuan_Boxes_and_Pens
the correct frontend should be "Zarlink MT352" which I compiled as module into the kernel.
However lsmod (attached below) shows that the mt352 module is not loaded automatically when the stick was plugged in.
When I load it manually (modprobe -v mt352) and dvbtune again, the system freezes after a few seconds.
Your help would be highly appreciated!

Best regards,

Frank
