[pvrusb2] Persistent device nodes

[Jan Ceuleers]

Hi there.

My cable operator is forcing me to go digital, by discontinuing my 
favourite channels on the analogue side.  I have four HVR-1900 tuners, 
two of which I intend to hook up to STBs while the other two will remain 
on the analogue side.

So I now have the problem of device name persistency for the first time. 
Certainly in terms of the /dev/video* device nodes, but since I'd also 
like to use the IR blaster capabilities of the HVR-1900 to control the 
STBs I also have the problem in respect of the LIRC device nodes.

I was wondering if I really have to attack this problem via udev, or 
whether the problem might already have been solved for me by the 
availability of links to the device nodes under /sys/class/pvrusb2/sn-*

Since there are circular references I can't just find /sys/class/pvrusb2 
-L -type l or type c

Thanks, Jan
