No depth channel publishing when using multiple Femto Bolt cameras

[Shepherd1226]

Hello, I'm using the multi_camera launch config to control two Femto Bolt cameras. Only the camera launched first is publishing the depth channels. The camera launched second is not publishing anything in the depth channel. The color channel is working well. Besides, both cameras are all tested in single-camera setting and are all working well. Attached is the launch logs in debug log level. Any suggestions would be helpful! Thanks in advance.

Sorry for the late reply. This issue looks like it might be related to USB bandwidth or buffer limitations when running multiple cameras simultaneously.

Please try increasing the usbfs_memory_mb value to allocate more USB transfer buffer memory. You can do this by running the following command:

echo 128 | sudo tee /sys/module/usbcore/parameters/usbfs_memory_mb
