thank you that seems very good solution
however
when i do pd -listdev my audio device and mididevices are on the same list
so if for example my usb audio is #2 and i unplug device #1 then usb audio becomes #1

this is why i thought audioaddoutdev will be best ,because this way PD knows exactly what to look for

@kazeko -audioaddoutdev should work here. Any errors printed? What is the output of -listdev when your interfaces are connected? You can save the pd log to a file when running headless by starting pd up with -stderr 2> log.txt, using that will overwrite log.txt with the stuff pd would normally print to the console, -stderr 2>> log.txt will append to log.txt instead of overwrite it.

i think i got it

turn out that hidden ~/.pdsettings file allready consists audio settings for PD,and because i run my
patch from rc.local ,pure data takes configuration from that file
so eventualy when i do not use any commands when starting PD it is all fine and audio card is automatically assigned regardles of which usb port it is in

thank you anyways
