udev rules from package stlink are not being parsed and triggered

[Mbk Kamble]

Hello,
  Newbie about udev concepts here. I included stlink package as part
of my package list in my system configuration. I can see that there
are rules files under /run/current-system/profile/etc/udev/rules.d/
like so:

sh> ls -l /run/current-system/profile/etc/udev/rules.d/
total 16
lrwxrwxrwx 1 root root 91 Dec 31  1969 49-stlinkv1.rules ->
/gnu/store/zpqb5vydhxkr5ggw767m4hkpi8263yvz-stlink-1.7.0/etc/udev/rules.d/49-stlinkv1.rules
lrwxrwxrwx 1 root root 93 Dec 31  1969 49-stlinkv2-1.rules ->
/gnu/store/zpqb5vydhxkr5ggw767m4hkpi8263yvz-stlink-1.7.0/etc/udev/rules.d/49-stlinkv2-1.rules
lrwxrwxrwx 1 root root 91 Dec 31  1969 49-stlinkv2.rules ->
/gnu/store/zpqb5vydhxkr5ggw767m4hkpi8263yvz-stlink-1.7.0/etc/udev/rules.d/49-stlinkv2.rules
lrwxrwxrwx 1 root root 91 Dec 31  1969 49-stlinkv3.rules ->
/gnu/store/zpqb5vydhxkr5ggw767m4hkpi8263yvz-stlink-1.7.0/etc/udev/rules.d/49-stlinkv3.rules

I using the stlink V2 usb device. So when I plug in the stlink v2,
udev should create a symlink  /dev/stlinkv2_blah
But that is not happening.

I also did a
sh> sudo udevadm test (udevadm info -q path -n /dev/bus/usb/002/006)
that shows it is reading only files from eudev pacakge
with output lines like Reading rules file:
/gnu/store/2l46l7628xyrpwzrymzd3bgrz3n8zf2x-eudev-3.2.11/lib/udev/rules.d/
etc

Seeking help

Thanks,
