Im starting my Raspberry Pi. Connecting the EOS 450Da. After this switched on the mirror lock in the camera settings. After that I'm starting KStars and EKos and connecting the camera to it (USB). After that I can take a test exposure. When I turn on the mirror lock time to 2 secs the camera seems to crash. The camera is still working fine but its not respondig to usb signals. I'm also not able to disconnect the camera after that.
I'm also getting an Error Message: Mirror lock feature is not yet implemented for this camera model.
After that I have to restart the camera and KStars. If I turn off the Mirror lock time everything works fine (except Mirror Lock).
