While setting up an environment with 6 Azure Kinects, I encounter slow depth image processing times when all six cameras are running simultaneously, despite no issues when only four cameras are active. Moreover, when two Kinects are plugged into adjacent USB ports on my computer, one of them experiences flickering and dropped frames. This problem does not occur if a gap is left between the Kinects plugged into the USB ports.
To Reproduce
Six Azure Kinects should operate simultaneously without any warnings about slow depth image processing times. Kinects should also be able to function properly when plugged into adjacent USB ports without experiencing flickering or dropped frames.
Logs
The following warnings are repeatedly generated when running six Kinects:
[ warning ] : depth_engine_thread(). Depth image processing is too slow at X ms (this may be transient).
(X ranges from 34 ms to 56 ms)
