Hi Mario,

Now with kernel 2.6.32-rc3 (and 2.6.31.1) the modules seems to be
loaded fine, but tzap/kaffeine/mplayer can not tune to a channel:

dmesg says:
dvb-usb: found a 'TwinhanDTV USB-Ter USB1.1 / Magic Box I / HAMA USB1.1 DVB-T device' in warm state.
dvb-usb: will use the device's hardware PID filter (table count: 16).
DVB: registering new adapter (TwinhanDTV USB-Ter USB1.1 / Magic Box I / HAMA USB1.1 DVB-T device)
DVB: registering adapter 0 frontend 0 (DiBcom 3000M-B DVB-T)...
dibusb: This device has the Thomson Cable onboard. Which is default.
input: IR-receiver inside an USB DVB receiver as /devices/pci0000:00/0000:00:04.0/usb4/4-2/input/input5
dvb-usb: schedule remote query interval to 150 msecs.
dvb-usb: TwinhanDTV USB-Ter USB1.1 / Magic Box I / HAMA USB1.1 DVB-T device successfully initialized and connected.
usbcore: registered new interface driver dvb_usb_dibusb_mb

[..]
and so on. The signal-values are zero or near zero, but when i boot the old kernel 2.6.30.8, t can tune without problems.

In a personal email to me you are saying that the differences between dibusb-common.c in 2.6.30.8 and 2.6.32-rc3 are the main cause for the problem.

Is it possible for you find out which exact change is causing the trouble?

With the v4l-dvb-hg-repository it is possible to get each intemediate version of this file. Afaics, there is only 3 modifications for the timeframe we are talking about.

best regards,
