Hi,
so I tried to look for some kind of info to help me identify the tuners, this is the most interesting bit I guess:


VDR-test-cellar (SDB1): udevadm info --query=all --name=/dev/dvb/adapter1/frontend0 --attribute-walk looking at device '/devices/pci0000:00/0000:00:0d.0/0000:02:00.0/dvb/dvb1.frontend0':
    KERNEL=="dvb1.frontend0"
    SUBSYSTEM=="dvb"
    DRIVER==""

You can use this command :
udevadm info -a -p $(udevadm info -q path -n /dev/your/path)

to get the complete tree and watch if you can differentiate your front end with one or more attributes of the subsystems.

At the moment I cannot find anything to identify the 4 Tuners on the Cine S2, the FF on 01:06 is easy. I got hit by tuning problems a few days ago as the tuner without a cable was given FE3/0. The FF got FE4/0 at that time. I'm wondering if the DDBridge driver will always number in the correct order.

So I guess I'll try to make the FF FE0/0, and hope that the DDBRidge driver will do the rest.

Cheers Brian

Hi,
well Its exactly what I was doing, and I cant see a difference. Here an example of two of the Cine S2 Tuners:

VDR-test-cellar (SDB1): udevadm info -a -p $(udevadm info -q path -n /dev/dvb/adapter3/frontend0)

Udevadm info starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.

Thanks for the suggestions though.

So now I'm looking for other ideas. Hows about blacklisting DDBridge and then modprobeing it before VDR starts? That way the FF will get FE0/0, and I assume the Cine S2 tuners will enumerate
in ascending order.


Cheers Brian
