BT controllers unable to work in 7.0.1, require power off/on in emulator and Retroarch menu, works perfectly fine on version 18.07.13
see my forum post please describing this issue. https://forum.recalbox.com/topic/21922/fresh-install-and-not-able-to-get-hotkey-to-work-on-bt-controller
Basically i have an old image of 18.07.13 on my pi3 , my BT controllers work PERFECTLY on it. When i lay down 7.0.1 new fresh image, setup my Bt controllers, they work in ES fine, but soon as i go into emulator to start a game the controller doesn't work. I power off the controller and back on and it works. Then if I hit hotkey-B to get into Retroarch it brings up the menu for Retroarch but i have to power/on again. then when i go back to game in emulator again have to power off/on. when i exit game back to ES , controller works perfect doesn't require power off/on... this is 7.0.1.. again my old 18.07.13 .img file i found which still has the same BT controllers configured works fine. i can even add new BT controllers to the the old 18.07.13 img and they work.. if i add those same brand new BT controllers to 7.0.1 i have the same issue. so logically nothing is wrong with my pi 3 nor my Bt controllers because they work perfect under 18.07.13.. I have provided attached config files if you need any other files let me know. I can repro this at will using my .img files just give me steps and i can do anything you need. i really really :) want to use 7.0.1 but can't.
