Coral USB on Proxmox LXC
See original GitHub issueHello,
Can’t get Frigate working with Google Coral USB accelerator. I am running Proxmox 7.0, inside I have LXC container running Debian 10 turnkey core 16 image. Inside Debian I am running Frigate docker container. In log files I allways get error “No EdgeTPU detected”.
