How to see if Coral USB is being used

[wpeterw]

I've installed and configured my Coral USB. Is there a way to see (logging ?) if the Coral is beeing used ? I see interference speeds of 200ms+.

Likely your Coral is not being used if the inference speed is 200ms, it should probably be less than 60ms even on a slow machine and 20ms on a good one.

Post your sanitised docker command or compose file, I didn't have to install any Coral stuff on the host os, everything that was needed was in the container.

You are right:

frigate | * Serving Flask app "detect_objects" (lazy loading) frigate | * Environment: development frigate | * Debug mode: off frigate | No EdgeTPU detected. Falling back to CPU.

Now to find out why, my Coral USB shows up as:

Bus 002 Device 004: ID 1a6e:089a Global Unichip Corp. So, not as a Google device.

There is an issue #381 where it is not found on boot and restarting the container fixes it. You could try that.

I got it working now, I've noticed the usb path changes when unpluggin/pluggin in the device.

On USB coral, the white led blinks when it's in use. Easy way to check things out.
