Hello Team,

I don't seem to be able to install mu USB Coral TPU within Proxmox 9.
root@proxmox:~# lsusb | grep -E "(1a6e:089a|18d1:9302)"
Bus 002 Device 004: ID 1a6e:089a Global Unichip Corp.

I installed pve headers but I get:

# Ensure proper kernel headers

I also tried with https://coral.ai/software/ website but apt-key is not working anymore.

Merci

How are you using the Coral USB TPU? I'm curious what benefit you get from installing the driver on the PVE host.
 
I use it with lxc as I get better performances than within a vm. So I don't have missed frames anymore on the detection streams.

And you?
 
You don't need any driver on the host in order to use the USB coral in an lxc.

You just pass the usb port to the container. The container needs to have the driver installed.
 
I'm using it in an unprivileged lxc running frigate (docker). I did not find it necessary to install a driver on the PVE host. The mini-pcie versions though do require the driver on the host (for lxc use).

I have then the same setup. So not sure why it was not working. Can you show your.conf special cmds to pass the device? Merci
 
The pertinent parts of lxc.conf for coral access and igpu encoder.

Code: 
features: keyctl=1,nesting=1
unprivileged: 1
dev0: /dev/dri/renderD128,gid=106
lxc.cgroup2.devices.allow: c 189:* rwm
lxc.mount.entry: /dev/bus/usb dev/bus/usb none bind,optional,create=dir

106 is the render group in my debian docker lxc. I am aware this exposes all usb devices to this container, so I am open to ways to improve that.

udev rules to enable unprivileged access to usb device (pre/post initialised state). This is more permissive than I'd like so I need to sort that out.

Code: 
#/etc/udev/rules.d/71-edgetpu.rules
SUBSYSTEMS=="usb", ATTRS{idVendor}=="1a6e", ATTRS{idProduct}=="089a", MODE="0666"
SUBSYSTEMS=="usb", ATTRS{idVendor}=="18d1", ATTRS{idProduct}=="9302", MODE="0666"

With the USB coral, no driver as such is needed. Just the appropriate libraries.
