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".
