Hi Martin,

Thanks for the answer, and that's an approach I've taken with other
projects, but we'd rather the user didn't have to take any action at all
- i.e. the entry was already there... After all, every other device in
the original file
/etc/udev/rules.d/78-mm-usb-device-blacklist-local.rules got there
somehow, so why not ours?

cheers,
Adam
