Hi, I install batocera 5.17 on lenovo G400s 20244. I try to use my ps3 bluetooth controllers, but its only works via usb (both: SHANWAN and SZMY-POWER). I tried to config via on screen menu, but not found any device. I tried changing driver on config file and using a usb dongle, but didn't work. My dmesg show this:
dmesg | grep Bluetooth

[ 7.631476] Bluetooth: Core ver 2.22

So, I tried copying the firmware (downloaded from https://kernel.googlesource.com/pub/scm/linux/kernel/git/firmware/linux-firmware/+/4a91e8c9f1e433143cf900487fbef01aa8b4c869/ar3k) to /lib/firmware/ar3k and rebooting the system, but on every reboot this directory and his content was erased.
Any help is welcome.
