Hello,

I'm trying to run a ToF sensor instead of the HIRes camera on HW Sensor ID:3 in this [configuration](https://docs.modalai.com/voxl2-camera-configs/#c11---front-stereo-rear-stereo-hires-and-tracking) but camera server is not recognizing the device sometimes. When I run ```voxl-camera-server -l``` sometimes the camera shows on the device list but other times it does not. 
I believe in System Image 1.4.1, ToF has support on all 6 camera interfaces?

Thanks

You need to use a supported camera configuration. You cannot plug different sensors into different locations. C6 and C9 are supported for TOF. https://docs.modalai.com/voxl2-camera-configs/

If different sensors are plugged into different locations, undetermined behavior will occur
