  • Code can't find my device even though it is listed in Device Manager

Hello community,

I have an OAK-1-Lite which is connected via a USB-3 to USB-C cable to my Laptop. The Laptop is connected to a power station and the USB-Port is a SuperSpeed port.

I have tried running my own code and the rgb_preview but both codes give me the following error message:
"RuntimeError: Cannot find any device with given deviceInfo"

I have also tried running the dephtai-viewer but it also can't find my camera.

The last thing I have tried is running the code from the following site to discover all connected devices:
https://docs.luxonis.com/software/depthai/examples/device_information/
But I also got an error saying "Couldn't find any available devices.

What is weird to me, is that the camera itself gets recognized by my laptop. When checking the Device Manager I have a Movidius MyriadX listed under USB-devices.

I have also tried running the following code snippet from a different ask but it didn't list anything:
import depthai

for device in depthai.Device.getAllAvailableDevices():

print(f"{device.getMxId()} {device.state}")

Is there a step in the configuration that I have forgotten or is there something faulty with my camera?

Best wishes,

Johnny

    Maybe as an addendum in case it is relevant:

    I am running my code on a Windows 11 machine in WSL2

      I tried running this code but it told me, that it uses a deprecated way of attaching a USB-device to WSL and redirected me to this documentation:
      https://learn.microsoft.com/en-gb/windows/wsl/connect-usb#attach-a-usb-device

      I followed it and it briefly worked. But after closing the bash-console and reopening it, it didn't see the USB device again and the code in the documentation didn't work anymore.
      I'll have to try this again tomorrow.

        Yes, that's how it should be done. Keep in mind this is a daemon that closes when the device reboots or the wsl is closed down. I think the --attach option has -a (or similar) to signify automatic mode so you don't have to manually reattach the device when you disconnect it.

        Thanks,

          Okay, thank you so much for the help. I have pivoted to just running the code on windows instead of WSL since it eliminates that problem. But it also worked in WSL with the documentation.
