Crazyflie USB power and IMU startup

[VitalyFan]

Hello everyone, I need help pls
I'm using a Crazyflie 2.1 and a BigQuad Deck.
When I connect the Crazyflie 2.1 via USB, the client does not show the drone's orientation. I assume that the IMU does not start when powered via USB. When I connect the battery and then connect USB, I start seeing the drone's tilt.

Could you please tell me if there is a software-based shutdown of the IMU when powered via USB, and whether it's possible to start the IMU via USB? Does the fact that I'm also using a BigQuad Deck affect this?

Hello @VitalyFan!

There shouldn't be any software-based shutdown for the IMU. In my cfclient's Flight Tab, I can see the orientation of the Crazyflie when it's connected via USB regardless the battery connection.

Could you check if you're using a charging-only USB cable? This is a common mistake that prevents data transferring.

Let us know if you managed to figure it out or if we need to investigate this further.

I just changed my USB-cable and now It's working. Thanks for your answer!
