ZED Box Mini exposes only one Argus device with two ZED X One GS

Suveen · April 22, 2026, 7:23am

Hardware: ZED Box Mini (Orin NX 8GB), 2x ZED X One GS

Each camera streams fine alone, but nothing lets both stream concurrently:

Single sl.CameraOne — OK
Two sl.CameraOne (one process, or two processes) — FAIL
sl.Camera.set_virtual_stereo_from_serial_numbers(...) — FAIL
ZED_Media_Server --cli — FAIL, crashes nvargus-daemon

Every failure is the same Argus error:
(Argus) Error AlreadyAllocated: Device 0 (of 1) is in use

Kernel side looks healthy — both sensors bind in dmesg with correct serials, both /dev/video{0,1} present, CameraOne.get_device_list() returns both serials as AVAILABLE. The collapse happens in nvargus-daemon, which only advertises one device.

Docs list Box Mini as a supported host for dual ZED X One, so I assume this should work. Has anyone gotten two ZED X One GS streaming concurrently on a Box Mini? Is there a DTBO / driver update, or a step missing?

Hi @Suveen
Welcome to the StereoLabs community.

To assist you better, we need additional information regarding your device’s condition and system setup.

Please open a terminal console (Ctrl+Alt+t) and run these commands:

sudo ZED_Diagnostic --dmesg
sudo ZED_Diagnostic -c

After executing the commands, kindly send me the content of the files dmesg.log and ZED_Diagnostic_Results.json located in the folder where the commands were run.

thank you for the quick reply.

When testing a custom kernel, it is recommended that you create a backup of

the original kernel and add a new entry to this file so that the device can

fallback to the original kernel. To do this:



1, Make a backup of the original kernel

sudo cp /boot/Image /boot/Image.backup



2, Copy your custom kernel into /boot/Image



3, Uncomment below menu setting lines for the original kernel



4, Reboot

The ZED X Driver detects both cameras:

[  369.622364] zedx 2-0011: zedx_probe: Serial Number : 303626954

[  369.954062] zedx 2-0010: zedx_probe: Serial Number : 308588307

What’s the output of the command ZED_Explorer -a?
Can you open both simultaneously using the ZED_Studio tool?
