Oak D Lite made some progress but there's issues. What cables do you recommend to connect the Oak D Lite

[jerrynsr]

I decided to start out with the python3 depthai examples and test. In this video I'm running rgb_preview.py example.. note: nothing is published to ROS2 here. I am just remotely displaying the video stream to my Linux Desktop. The ROS2 examples start ok, display the pointcloud data, but will stop withing 20 seconds of running. I am using decent quality USB3.1 cables, and a power T.
I figured the simple rgb_preview.py script had a blocking issue then I should fix that first. I looks like the blocking issue is caused
by the usb 3.1 cables I chose.
Here's the issue:
File "./rgb_preview.py", line 34, in
inRgb = qRgb.get() # blocking call, will wait until a new data has arrived

The problem is the code running on the Luxonis Oak D Lite. I tested with many high quality USBC cables ranging from 6" to 1 ft long.
I tested with my RPI4, Intel Hades Canyon NUC, and M1 MacStudio. Also with the same result, disconnect after 20 seconds or so.
I had to throttle down the connection adding: ", usb2Mode=True" when setting up the device pipeline.
I don't think it will be too much of a problem but I wish this information was public because I would of purchased a RealSense camera instead.

Hey @jerrynsr! It sounds like you've arrived at a workable solution. Anything else here that is unresolved?

[jerrynsr]

Nope. Image tracking is working in USB 2.0 mode. :) I think I'm going to modify the Luxonis camera mount to add a camera tilt servo. I can cover camera panning with the robot base.

I’ve noticed the camera only works well with high end cables, when the cable quality is bad i need to throttle down using the usb2 mode. I don’t see this 20 second limit with the cable that came with the OakD cam.
