I am currently using a bluetooth dongle and PS3 controller for Retropie 3.0 BETA. It works brilliantly, but if I shut down the Pi and boot it up again, say the next day, the Bluetooth dongle doesnt always activate. Its hit and miss as to whether it will turn on or not. I end up shutting down multiple times before it will turn on.
It has a small blue led that flashes when it is working and this does not happen all the time. weirdly, however, it always starts flashing if i use the command sudo reboot, but doesnt when i switch on the pi.
Is there something I need to change to make sure its always on at startup?
I have an update. If I remove the dongle prior to turning on, turn on the Pi and then plug in the dongle, it works. But it will not work if its already in the USB slot prior to booting. Anyone know what this could be?
