Proxmox + Dell Optiplex not recognising USB Coral as USB 3.0 device #782

Open qupterra opened 11 months ago

Hi all,

Using a Dell Optiplex 7060 with a USB Coral accelerator, having issues getting the device to recognise as USB 3.0

My use case is running Frigate in a docker container, seeing inferencing speeds of ~70-80ms Dell Optiplex > Proxmox > Debian VM > Docker Container

On the Proxmox host itself, it shows as a device under the USB 2.0 hub (Bus 001)

Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 004: ID 18d1:9302 Google Inc.
Bus 001 Device 002: ID 10c4:ea60 Silicon Labs CP210x UART Bridge
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

I've confirmed that the USB Coral is able to function at USB 3.0 speeds on another device (~10ms inferencing speed), using the same cable that it is connected to the Dell with and am unsure what else to try.

My next step will be to try to source a separate PCI-E USB card and see if it will detect properly using a device that doesn't rely on Dell's USB hardware and hope that drivers will better support the Coral and allow it to run at full USB 3.0 speeds.

I have installed a secondary PCI-E USB card and still encounter the same issue with the Coral only being recognised as a USB 2.0 device.
