I’m unable to save a .svo2 file using the ZED\_Explorer command line `--output` option.

Camera: ZED XOne GS

[Stereolabs](https://www.stereolabs.com/) SDK: 5.0.5

ZED\_Explorer can connect to the camera when the GUI opens and shows the camera when listing all the devices. I only have one camera attached to the computer.

```auto
~$ ZED_Explorer -a
## Cam 0 ##
 Model : "ZED XOne GS"
 S/N : <omitted>
 State : "AVAILABLE"
 Path : /dev/i2c-9
 ID : 0
 Type : "GMSL"
********************

~$ ZED_Explorer -i 0 -o test.svo2
Can not open the ZED, please connect it to another USB port.

```

Hi @And  
This is probably a bug in the ZED Explorer tool.  
Before reporting a bug to the team, please check if the latest v5.0.6 has already solved the issue.

Thanks for the suggestion. I updated to 5.0.6 and the issue persists. The ZED\_Explorer GUI still works.

```auto

$ZED_Explorer -v
Stereolabs ZED SDK Version : 5.0.6

$ZED_Explorer -a
## Cam 0 ##
 Model : "ZED XOne GS"
 S/N :  
 State : "AVAILABLE"
 Path : /dev/i2c-9
 ID : 0
 Type : "GMSL"
********************

$ZED_Explorer -o test.svo2
Can not open the ZED, please connect it to another USB port.

```

I suppose ZED Explorer does not identify the ZED X One, and it tries to open a ZED X.  
Please try to specify the serial number:

`ZED_Explorer --sn <serial> -o test.svo2`

In any case, I’m opening a bug report for this.

I tried the `--sn ` option and I get the same response:

`Can not open the ZED, please connect it to another USB port.`

I checked the serial number a few times to make sure I entered it correctly.

I’ll wait for the next SDK update and try again.

I forwarded the description of the problem to the SDK team to fix it with one of the next releases of the SDK.

This apparently hasn’t been resolved yet.

We are trying to interface ZED X One with ROS 2 on Jetson Orin Nano and have been failing to achieve the desired IMU update rate. So, we tried recording the SVO - ZED\_Explorer GUI works, but reports issues with dropped frames. ZED\_Explorer via command line reports the same error as reported by And. Tried providing the serial number, device index.

Trying to record the SVO via the API returns the error that the module is not supported with this device.

Any advice? Using [ZED SDK for JetPack 6.2.2 (L4T 36.5)](https://download.stereolabs.com/zedsdk/5.4/l4t36.5/jetsons) 5.4 (Jetson Orin, CUDA 12.6)
