[linux-dvb] Hauppage Nexus CA is not detecting frontend driver

[timkaiser@t-online.de (Tim Kaiser)]

Hi!
The card is not running.
It is a problem with the frontend driver.

There was a problem with 2.6.9 and the I2C driver. 
Sensors gave me no output.
Patching the kernel to 2.6.10RC1 has the following result:
---sensors---
tim@goofy:~$ sensors
pcf8574-i2c-2-21
Adapter: Octal/Technotrend DVB-C for iTV

pcf8591-i2c-1-48
Adapter: SMBus I801 adapter at e800
Chan. 0:    2.55 V
Chan. 1:    2.55 V
Chan. 2:    2.55 V
Chan. 3:    2.55 V
Output:     0.00 V (enabled)
------end sensors-------


I've compiled all the drivers with 2.6.9, 2.6.10-RC1 and the CVS version of 
linuxtv.org.
The result is the the same with all versions:
---dmesg----
adapter has MAC addr = 00:d0:5c:24:43:e6

saa7146_vv: saa7146 (0): registered device video0 [v4l2]
dvb-ttpci: found av7110-0
---end dmesg----

I tried insmoding all frontends into the Kernel.

---Text in qconf----------
If you don't know what tuner module is soldered on your
DVB adapter simply enable all supported frontends, the
right one will get autodetected.
---end text qconf----------

I think czap should autodetect the right frontend:
------czap---------

-----end czap---

here my lsmod output:

I tried to insert only the 2 cable relevant frontends. The result is the same 
like described above.

The device video0 seems to work fine.
Here a hardwarescan by xawtv:
------xawtv-----

-----end xawtv---------

I really have no idea what to do now.

Can somebody help me, PLEASE.

Best regards
