Serial port issue nrf52840 DK

I tried deploying a simple audio recognition module on the nrf52840 DK, but no COM port is detected. When I run edge-impulse-daemon it responds with no devices connected through the serial port. How do I fix this issue?

Hello @Etolani,

Can you make sure your USB port works and your USB cable support data transfer?
Can you see your device in your device manager on Windows?
Did you managed to flash the default Edge Impulse firmware properly?
I cannot remember for this device but on some of our officially supported device, you need to click the reset button before running the edge-impulse-daemon.
