Comment # 2 on bug 1039583 from Michal Suchanek

I can wait quite a while (minutes) and it is not supported anyway. Do the
bluetooth modules get loaded only after the script finishes?

I was trying to write a rule that enables the device when it is plugged in
because the default bluez configuration does not do that.

I guess this is not really relevant for bluetooth devices because if you search
really hard you can find a way to configure bluez to automagically enable them.

Still the fact that you cannot use the device in an udev rule for the device is
kind of not good.
