I couldn't reopen https://github.com/stereolabs/zed-ros-wrapper/issues/249, thus I created this new issue.

Hi @maxpolzin thank you for the correct behavior. Opening a new issue and tagging the closed one is indeed the right way to act.

I'm sorry, but the behavior that you describe is strictly related to the carrier board and to how it initializes the USB controller. We provided a workaround for this on the ZED2 and ZED2i with the reboot command that forces a re-initialization of the camera when the USB controller is ready, but unfortunately, this cannot be used with the ZED Mini.

The only available workaround is to reset the power of the USB controller of the carrier board to force a re-initialization of all the connected devices, but this does not work with all the controller models.

You can try to adapt this tool to your requirements: https://github.com/obraun-sl/usb_power_cycle

Thx for your prompt response @Myzhar and the clarification on the subject. I'll look into the power-cycling and note updates in this issue.

My solution is switching to our Zed2i which seems to work fine.
