Sorry ,We have not been able to reproduce the issues you mentioned on both Raspberry Pi 4 and Raspberry Pi 5. Below is a screenshot of Raspberry Pi 4.
What was the status of the Mega when you encountered the issue? Was the LED indicator functioning properly? Additionally, it is recommended to try using a different USB 3.0 cable for cross-verification.
Did this issue occur sporadically? Could you please provide the issue log
Thank for your quick response!
This seems to have been caused by systemd/user manager constantly restarting lightdm user session every 10 seconds. This starts/stops a lot of services and seems to interfere with Orbbec RGB camera stream. Possibly related to v4l2, I saw this on the system logs:
Jun 18 12:08:42 berry pipewire[13509]: [0:10:06.086660015] [13564] ERROR UVC uvcvideo.cpp:463 Camera /base/scb/pcie@7d500000/pci@0,0/usb@0,0-2:1.2-2bc5:0669 (Orbbec Femto Mega 3D Camera: Or) doesn't expose any supported format
After I stopped lightdm with sudo systemctl stop lightdm
the problem went away
Femto Mega seems to stop reading RGB camera after running for ~10 seconds on Raspbery Pi 4. The device was powered via the separate power source using barreljack and connected to RPi4 with USB3 A -> USB C cable
