### Basic Information: Printer Model: Elegoo Neptune 4 Pro MCU / Printerboard: ZNP-K1 (OpenNept4une) Host / SBC: Fluidd klippy.log ### Describe your issue: Hey! I’ve been trying my best to find a way to add two cameras to my printer, but no matter what I do, everything goes wrong. I’m using a usb hub to connect my cameras to the only usb port. Here’s my latest crowsnest.conf and crowsnest.log below… ```auto [crowsnest] log_path: ~/printer_data/logs/crowsnest.log log_level: verbose # Valid Options are quiet/verbose/debug delete_log: true # Deletes log on every restart, if set to true [cam 1] mode: ustreamer # ustreamer - Provides mjpg and snapshots.

I have tried multiple cameras, usb hubs, power options for the usb hubs and device names for each camera. No matter what I do, only one camera is on each time I fix and reboot the printer. Nothing has helped me so far. I hope you can 🙂 ---

It looks like there’s only one V4L device detected, so I think your first step needs to be making sure that both cameras are detected and working in Linux before trying to configure crowsnest to use them. ---

I also plugged in a new camera. ```auto [05/06/24 20:27:18] crowsnest: crowsnest - A webcam Service for multiple Cams and Stream Services.
