[linux-dvb] Re: Firmware won't upload

[Q <raid517@fairadsl.co.uk>]

OK I did as you suggested. This is the output I got from the command you
suggested:

[root@raid517 root]# ls -l /dev/dvb/adapter0
total 0
crwxrwxrwx  1 root video 250, 1 2004-08-17 01:26 audio0
crwxrwxrwx  1 root video 250, 6 2004-08-17 01:26 ca0
crwxrwxrwx  1 root video 250, 4 2004-08-17 01:26 demux0

 As you can see the devices do appear to be correctly listed. Unless you
can see something missing. I used the script supplied by linuxtv.org to
create these devices MAKEDEV-DVB.sh which I believe simply automates
running the mknod command. I have tried removing the devices and
rebuilding them again. I have not yet tried changing the adapter number
because I don't know how to tell scan to do this. It doesn't appear to
be listed in the docs. However I am suspicious as to whether the OS
actually sees these devices as real devices to begin with. The fact that
they are there but the OS claims that they don't even exist, is to say
the least bemusing.Since I have no other DVB adapters installed except
this one, wouldn't you assume that this would by definition default to
frontend0?

I can only make guess in this regard.

Perhaps you guys know better?

I wonder if the device major number change is the problem.

Check ls -l 
/dev/dvb/adapter0

and you should see the device numbers for each device.  The other one
is either 250 or 212.  

You could check if changing the device number would change anything.
Devices are made using the mknod command, i.e. you can try removing
the device with rm then making the new one with the same name using
mknod.  (see man mknod for details)  Do not change the minor numbers.
The device type is seen as the first character of the permissions list
in the ls -l listing.
