EdgeTPU (Coral USB) errors

[itlists]

Hello,

I have a Coral USB which is detected by unRaid and works in Frigate.

The device is passed into the container (see screenshot).

I've added the below to Viseron config file:

edgetpu:
object_detector:
cameras:
cam_front:
fps: 1
scan_on_motion_only: true
labels:
- label: person
confidence: 0.8
trigger_event_recording: true

Logs show the following errors:

[ERROR ] [viseron.components.edgetpu.subprocess] - driver/usb/usb_driver.cc:1148] HandleQueuedBulkIn transfer in failed. Not found: USB transfer error 5 [LibUsbDataInCallback]
[ERROR ] [viseron.watchdog.subprocess_watchdog] - Process subprocess.edgetpu.object_detector.process has exited, restarting
[ERROR ] [viseron.components.edgetpu.subprocess] - Error when trying to load EdgeTPU: Failed to load delegate from libedgetpu.so.1
[ERROR ] [viseron.components.edgetpu.subprocess] - Failed to make interpreter for device :0
[ERROR ] [viseron.components.edgetpu.subprocess] - Worker for device :0 failed to initialize
[ERROR ] [viseron.components.edgetpu] - Failed to initialize EdgeTPU

When this occurs, something else fails in the system because Frigate crashes with libedgetpu.so errors as well.
I have to disconnect and re-connect the Coral USB to get it working properly again.

Are you running Viseron and Frigate at the same time? If so, that's the issue. The Coral can only be used by one process at a time
