i try use ATTR{dev}=="14:20" but it change after reboot too =(
can i use number of pci slot ? or even more ?
-------- stop --------
but i have not answer =(
i try use externel program and it work now
i crеate file /root/device_namer
#!/bin/bash
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
if [ `echo $1 | grep "0000:02:03.0"| wc -l` != 0 ]; then
echo radio1;
exit 0;
fi
if [ `echo $1 | grep "0000:02:04.0"| wc -l` != 0 ]; then
echo radio2;
exit 0;
fi
i bad bash programmist =) then i add net line to /etc/udev/rules.d/10-local.rules
KERNEL=="audio*", PROGRAM="/root/device_namer %p", SYMLINK+="%c"
how it work : when system boot udev run some like
'/root/device_namer /devices/pci0000:00/0000:00:1e.0/0000:02:04.0/sound/card1/.tmp-14-20'
and create simlink what i need
