udev-161 dvbT kernel-2.6.35.5

[sibu xolo]

Greetings,  

I am attempting to set up DVBT on a computer with these:

--------cpu:  amd64 2 cores, gpu nvidia gforce  nouveau drm
--------o/s cblfslinux 64-bit kernel-2.6.35.5 udev-161  kde-4.4.5 
--------dvb device  Hauppauge wintvNovaT DVBT usb2

I have  the foollowing in /lib/firmware


dvb-usb-dib0700-01.fw       
dvb-usb-dib0700-1.20.fw 


#############  my udev rule looks like so:-

KERNEL="dvb*",
PROGRAM="/etc/udev/scripts/dvb.sh %k",  
ATTRS{serial}=="123456789a",
ATTRS{product}=="Nova-T Stick",
GROUP="video", 
MODE="0660",
SYMLINK+="Nova-T-usb2"

I used the said device successfully  in a build wih 2,6.28.8/udev-113 last 
year  but it appears   the setup for DVB on linux has changed recently.  
Accordingly guidance on where I am gping wrong would be much appreciated.

Yours sincerely

I sent the email above  to the list  a day or so ago and received no response. 
If I am on the wrong list I would be grateful if someone  aufait    inform me 
of the appropriate list.   Otherwise suggestions   of where I am going wrong  
would be much apprecuated.

as an update:-
I tested  the setup described above  on  a machine with kernel-2.6.31.6 and 
/dev/dvb/adapter0 is generated

I recall a  while back when DVB  drivers were not in the kernel.   Then they  
were  integrated within  thus requiring only a kernel compilation.  I came 
across the somewhat  ubuntified  wiki
( http://www.linuxtv.org/wiki/index.php/Bug_Report )
(which seems  to suggest the old method    is now needed..  I would  thus be 
grateful for some clarity  as per:-

Is  compiling the kernel  as up to 2.6.28.8 and  with prior selection of the 
appropriate devices under device/drivers/multimedia/video   sufficient or does 
one  now need  to follow the recipe given by the link above.

I have two dvbT devices avermedia-dbvT-usb2 (DEVICE1) and Hauppauge wintv 
NovatT-usb2(DEVICE2).  I am not a total novice at installing dvb on linux.  I 
have done so in the past on 

--kernels 2.6.17/2.6.19
--kernel-2.6.27/2.6.31
firmwares in /lib/irmware
AND Both worked  successfully on the above.

NOW after  the post(s) above  which provided no response,  I fiddled around 
like so:-

-------------------------------------------
-----------A) I compiled the kernel  for in-kernel drivers/modern V4L-api/with  
DEVICE1 in situ. On booting -  I obtained  /dev/dvb/adapter0.  Eureka.
I then  tried booting with DEVICE2 and  the machine dwelled   then reported 
that firmware file could not be found.  I  Then rebooted with DEVICE1 only to 
be met with the same message.  
I surmised that perhaps I should use the older api  marked depreciated as 
DECICE{1/2} are ~6 years old.

----------B)So I recompiled the kernel  with both devices attached  selecting 
v4l- depreciated  and compiled all as modules.  
After kernel installation   DEVICES{1/2} registered as /dev/dvb/adapter{0/1). 
Hurray  at last.
I removed the device did something else and rebooted the machine. with one 
device. On booting  I obntained the  'cant find firmware error as reported 
under A).  
I tried the other device  and onbbtained the same error.



I would be most grateful if someone on list could explain what is going on 
please.  I see 'patches' flying  and things looking ever so  busy and 
complicated  but no one seens inclined to  provide a modicum of guidance if 
only as a pointer to the appropriate list or if this is the appropriate list. 

In the words of JKGailbraith 'lets hope that  apparent 'complexities' are not 
devices for avoiding simple truths".
