I don't use the RUN command in my udev rule.  I just use ATTRS and MODE 
to allow all users to use the device. 
SUBSYSTEM=="usb", ATTRS{idVendor}=="<my vendor id>", MODE="0666"
So Assuming your RUN command is not the problem, perhaps you need 
SUBSYSTEM instead of DRIVER.

As for the RUN command, is it /sbin/fxload/ with a trailing slash?

I'm working in Fedora though, I don't know if the UDEV rules have 
differences from platform to platform.
