Mantis Q40: General Discussion

Information about the Product: Mantis Q40

A student is having issues with his Mantis Q40 staying connected to his Chromebook. His Chromebook is new this school year and we recently replaced the cord connecting the two devices thinking it was a cord issue. He says that the Mantis is saying, “Mantis Disconnected and/or Device Detected.” Any thoughts on why it is not staying connected? Thanks
