It didn't work. The $name that I get is in the form of usbdev1.8_ep00 still. However, I tried the following

BUS="usb", ACTION="add", <...etc...> , ENV{devpath}="$attr{busnum}/$attr{devnum}"
RUN+="/sbin/fxload -I /lib/firmware/foo.hex -D /dev/bus/usb/$env{devpath}"

Only that $devpath evaluates to 1/8 or 10/7, but the number must always be 3 digits with zeros filling the leading digits, e.g.

/dev/bus/usb/001/008 or /dev/bus/usb/010/007

I have no idea how to do this in the rules files without calling an external script.
