Couldn't read data from stream: 'rgb' (X_LINK_ERROR)

Hello,
I got the following error following the hello-world tutorial script

Traceback (most recent call last):
  File "C:/Desktop/hello-world.py", line 63, in <module>
    in_rgb = q_rgb.tryGet()
RuntimeError: Communication exception - possible device error/misconfiguration. Original message 'Couldn't read data from stream: 'rgb' (X_LINK_ERROR)'

Sorry about the cable. What USB cable are you using and which host? Generally this can happen if a USB3 device (e.g. OAK-D) is used with a USB3 capable host (e.g. a new Windows machine) but a USB2 cable is used.

Most/all USBC charger cables are actually USB2. To debug, you could either try a known-USB3 cable or stick with the USB2 cable (assuming it is USB2) and change the line per here:

https://docs.luxonis.com/en/latest/pages/troubleshooting/#forcing-usb2-communication

Where you see dai.Device, change that line to have dai.Device(pipeline, usb2Mode=True).

Thanks and sorry again about the trouble.
