This command lists the complete names of the variables you can use in
the udev rules file.

udevadm info --query=all --attribute-walk --name=/dev/whatever.the.name.is

Interesting that the serial value is a different name than the one shown
in 'lsusb -v' or in 'udevadm monitor' when the device is plugged in. Is
more really merrier?

My rule should be:

BUS=="usb", ATTRS{serial}=="A7004luX", MODE="0666", SYMLINK+="usbp2", 
OWNER="rst", GROUP="users"

Yours sincerely,
