PS3 controller, RPiZero1W, Bullseye

[rickticktock]

I say chaps,
I have been using a PS3 controller and a RPiZero to control the motors in my telescope over Bluetooth. Then I upgraded to Bullseye to get a better camera app. Now it won't work.
bluetoothctl shows other Bluetooth stuff but not the PS3 controller.
I installed with...
sudo apt update && sudo apt upgrade && sudo apt install libusb-dev && mkdir ~/sixpair &&
cd ~/sixpair &&
wget http://www.pabr.org/sixlinux/sixpair.c && gcc -o sixpair sixpair.c -lusb

The controller is recognised by a RPi4 running Bullseye, so it does work, with jstest even.
Do I
get a RPi4 for my telescope
roll back the OS issue
Use RetroPi? Does it do cameras?
connect the controller with a cable?
TTFN

You may have posted to the wrong forum - RetroPie is a retro-gaming oriented distribution, based on Raspberry Pi OS (and for the moment it's not supported on the RPI OS 'bullseye' release).

If your PS3 controller is already working, then probably you'd have to look into how the program used to read the inputs from it works with your telescope controls (connected via GPIO perhaps?). It may be that it's no longer functioning with 'bullseye' for various reasons, but without details on how this program works, it's just a guessing game trying to diagnose the issue.
