        Macbook pro 13" Retina

        System:  macOS Sierra 10.12 Beta (16A304a)

        Usb Serial Device: NEJE Laser  Engraver Printer

        Drive: CH34X USB-SERIAL DRIVER INSTALLATION INSTRUCTIONS Version:V1.0

        When NEJE connected my macbookPro, the Mac is borken, caused Four-languages-Error. Check "System Repor -> Hardware -> USB", NOT found any Usb Serial Device.

        Does anyone know what's going on?TKS.
