CAN bus does not work without USB connection

Support ODrive Pro Support

Hey,
I’m trying to control the ODrive Pro using CAN bus.
Can bus only works for me when the usb is plugged in.
Can I make Can bus work without the USB connected?
Also, Can CAN bus operate on USB 5V (no data) for making configurations without battery power?

Please review the grounding documentation in the CAN Guide.

On ODrive Pro, to operate the CAN you need to either provide DC power or supply power on the 12V axillary logic power input.

Thanks
And what about the USB connection?
When USB is connected, odrive transmits data on can bus, but when I remove the usb cable it stops. Is it intentional?

No, it is likely because of a ground issue, please check the documentation.
