Getting started with OAK-FFC-6P

Hi,
I'm trying to get started with the OAK-FFC-6P and I'm having trouble getting the basic things working, like connecting it to a PC.
Here are the steps I've done so far following https://docs.luxonis.com/projects/hardware/en/latest/pages/DM3390.html#developing-with-the-oak-ffc

1. plugged in a mono camera into the CAMA port
2. connected a USBC 3 cable to my Intel PC running Ubuntu 22.40. PG (power good?) LED lights up so I assume I don't actually need to use the barrel power jack.
3. ran sudo wget -qO- https://docs.luxonis.com/install_depthai.sh | bash, "No DespthAI device found!"
4. lsusb shows a new device: Bus 004 Device 093: ID 0525:a4a2 Netchip Technology, Inc. Linux-USB Ethernet/RNDIS Gadget
5. downloaded https://github.com/luxonis/depthai-python
6. ran python3 depthai-python/utilities/device_manager.py, "No devices found."
   
7. Plugged in a 5V center positive barrel jack to see if that would help, but same issue.
8. Pressed Reset buttons and power buttons
9. LED1 and LED2 stay unlit.
10. The heatsink is getting warm.
    
11. I can use ssh to login using ssh root@192.168.197.55

It's using an Intel kernel on an ARM Cortex-A53 processor? cool

Am I supposed to upload firmware to the board before using it? Do I need something on the microSD card?

Thanks
