USB Devices not being detected

[Matiplus]

Hi @xadox ,
1. Go to your VM -> Hardware -> add -> PCI device -> RAW device, and on the list try to find your device, something with name Google Inc or Coral. Is there is your device remember ID.
2. After that in proxmox prompt use command lspci -n to find hardware id. Something similar to 18d1:xxxx
3. Once you have a hardware ID, you can create a separate group for that device - instructions above.

Hmm.. I am wondering why it should be under PCI device, but the device it not there as well (for USB the same):

Have you tried this device on another computer? To confirm that it works correctly.
If the devices are in the same group IOMMU and one of the devices in that group is transferred to one of the VMs, it will not be visible, because all the devices in that group will be reserved for that VM.

At the moment I am not passing any devices through to any VM or LXC.
The Coral TPU is working fine under my Windows PC.

Try connecting another USB device to the same port, such as a flash drive or something else. This will give some indication
read, you may need to install drivers first

[SOLVED] Thread 'Google Coral USB Initialisation'

Jul 29, 2024

When following the Coral USB set up guide (https://coral.ai/docs/accelerator/get-started/#1-install-the-edge-tpu-runtime) I am able to get through adding the Debian package repository to my system but when I come to install I get the following error, would be grateful for some guidance on how to rectify.

Try connecting another USB device to the same port

Tested with several USB Sticks and USB HDDs.

Drivers for Coral TPU are installed, already:

Reinstalling Proxmox from scratch solved the prob:
