@NV4RE It's not related to the issue you mentioned. The issue you mentioned is about connection problems with a cb1. Your issue is just about crowsnest.log not showing the second identical camera. Crowsnest currently only shows the entry of |

I updated this issue to represent a feature request. Fyi this feature is internally already under development. |

@NV4RE I need some information for this issue to tackle it correctly. |
Hi, thanks for the follow-up. I apologize that I can't be of more help in testing the fix right now. I actually removed all the webcams from the machine a while back, so I can't send you the output or confirm whether the issue is resolved. However, I wanted to provide some additional information that might be helpful. Since the last time I interacted with this issue, I tried using multiple webcams with the machine, but from different models and brands. Unfortunately, the problem persisted regardless of the webcams used. This leads me to believe that the root cause might be related to the bandwidth limitations of the BTT Manta M8P's USB chip. It's possible it doesn't have enough capacity to handle multiple webcams efficiently. |

Ok, then I now understand why you mentioned #109. You are completely correct and the CB1 and CM4 are not capable of multiple cameras, as they only got one USB 2.0 interface.
I will focus in this issue on 1 as 2 got it's own issue. If you still have those 2 identical cams lying around, I would highly appreciate, if you could connect them shortly and get me the output. They don't have to run inside Crowsnest or similar, they just need to be connected to the USB ports. |
Hello, I've reinstalled the webcam, but the problem persists. Here's the output of {
