[Detector Support]: Even with correct mount points, Coral TPU is not found by Frigate on unprivileged LXC in Proxmox

[distante]

Describe the problem you are having

I am trying to get a Coral TPU to be detected by a frigate instance inside an LXC.

My proxmox host returns consistently this for lsusb

Bus 001 Device 002: ID 8087:8000 Intel Corp. Integrated Rate Matching Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 002: ID 8087:8008 Intel Corp. Integrated Rate Matching Hub

Bus 003 Device 003: ID 0a05:7211 Unknown Manufacturer hub
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

The root has on bus 4:

root@proxmox ~# ls -l /dev/bus/usb/004/
total 0
crw-rw-r-- 1 root root 189, 384 Mar 28 20:47 001
crw-rw-r-- 1 root root 189, 385 Mar 28 20:47 002

I am allowing that device to the LXC using their major and majors, as weell as mounting /dev/bus/usb/004

Inside the container, I U see the mounted devices:

root@frigate-lxc ~# ls -l /dev/bus/usb/004

crw-rw-r-- 1 nobody nogroup 189, 385 Mar 28 19:47 002

But when Frigate starts, it fails constanly due not detected TPU

I have seen #9970 and #9019 (comment) but it does not look like I have those problems (unless I am miss reading something)

#9019 might be helpful

[distante]

Hi. I already checked that, the error on that discussion was a wrong assigned bus. In my case the bus is correctly assign.

[NickM-27]

maybe try using /dev/bus/usb as a volume instead of device in the compose, that worked for some people

[distante]

It was a permissions problem I posted in #10732 (comment) what I did. Although I do not know if that is the best way.

[distante]

So after trying a lot of stuff, I tried something that I needed to get iGPU working on a Nextcloud LXC machine, allowing everyone to use the usb device.

On the proxmox host, I had call chmod 666 /dev/bus/usb/004/001 and chmod 666 /dev/bus/usb/004/002 and now it works.

I am not sure if a better way exists to be honest.

[marleyjaffe]

both of these chmod commands appear to be the same. Did you run the same command twice or is one of the two missing a change?

[distante]

One was 001 I documented what I did to my self here if you are interested.

[marleyjaffe]

Thank you for the great write up, unfortunately, I am still having issues, below is the output of the commands as you have in your post, can you assist my troubleshooting?

Not very clear what the difference is between the before and after initialization coral ACTION lines are, is the last line correct on your blog post? (doesn't seem like its causing the issue i'm facing currently)

I believe the above is the issue since the underlying 003 and 001 are not being passed through.

...

When I have the detectors: section commented out in the config, it works with out errors, when I uncomment I get the above errors.

Additionally, I accidentally ran chmod 666 /dev/bus/usb/ on my proxmox host... can you tell me what the original permissions on that folder are so I can reset them?

[marleyjaffe]

I additionally added the following lines to my lxc config as found here, but that did not solve anything.

usb1: host=18d1:9302,usb3=1
