Hi @crimsonnight, okay thanks for the additional information. I checked with the developers and this chipset is unfortunately not one that we have tested with the EyeX and as this hardware is now deprecated and replaced by the 4C, our best advice would be to try a powered USB3 hub if possible as this may mitigate the disconnection due to power loss. Also worth checking if the USB ports are set to turn off (or low power) when not in use, which is a setting configured within the BIOS of your system.
