When the In-Sight 8900 is connected via USB-C but does not appear in In-Sight Vision Suite and its LEDs flash red, the issue is typically caused by an insufficient power supply from the USB-C cable. The In-Sight 8900 requires a cable that meets the power delivery specifications outlined in the official documentation. Using a compliant cable will restore normal operation: the device will appear in In-Sight 8900 and the LEDs will turn green.
