Fedora14: udev and $tempnode

I am trying to get the Xilinx FPGA tools USB cables running under Fedora14
and have come up against a problem. The Xilinx system includes
a udev rules file that has a line entry like:

SUBSYSTEMS=="usb", ACTION=="add", ATTRS{idVendor}=="03fd",
ATTRS{idProduct}=="000d", RUN+="/sbin/fxload -v -t fx2 -I
/usr/share/xusb_emb.hex -D $tempnode"

After a bit of debugging, when I plug in the USB device the rule gets
activated but the value of $tempnode is "" (ie null string). The udev
documentation states that this gets filled in with the name of a temporary
device node....

Any ideas on why this is not happening with F14 (it works fine under RHEL5).
