Comment 2 for bug 38021

I have been working with the author of madfuload and we found a workaround. Apparently Dapper's udev variables don't resolve themselves correctly or something like that. Anyway, if you install madfuload and change the Transit line in /etc/udev/rules.d/42-madfuload.rules to use the -D option, it seems to work beautifully:

ACTION=="add", SUBSYSTEM=="usb", DEVPATH=="/*.0", ENV{PRODUCT}=="763/2806/*", RUN+="/usr/local/sbin/madfuload -l -D %E{DEVICE} -3 -f /usr/local/share/usb/maudio/ma006100.bin"

This is still a regression though, because it does not work out of the box (default flight-6 install).
