USB Device Node (with Ubuntu)

RyanLee

Hi,

Could you explain about the below situation for our better understanding about its working?

Before program running
the name of usb device node is "Intel Movidius Myriadx".

After program running
The name of the usb device node is "Intel Myriad VPU [Movidius Neural Compute Stick]"

As you can see the images, why the name of the usb device node is changed? We just hope to know its working to have better understanding about it.

Best regards,
Ryan.

Hi RyanLee ,
First when you connect the USB device to your computer, there's just default bootloader running, and VPU will show up as described. When you start a pipeline, depthai firmware will get uploaded to the device and booted, which will change the usb descriptor and also use USB3 (if possible). After that the pipeline/assets get uploaded to the VPU, and the whole app starts.
Thanks, Erik
