        I am developing a app for 3D printers that comunicate throught USB port to 3D printers, CNCs, etc; this most printers use Open Hardware like Arduino... etc... I Use poxis functions to comunicate whit the USB port like open(), write(), read(), close().. etc... at speeds of 200,000 bits per second ... if I Sandbox the app I lost accces to USB port. I read. https://developer.apple.com/library/content/documentation/DeviceDrivers/Conceptual/USBBook/USBIntro/USBIntro.html#//apple_ref/doc/uid/TP40002643-TPXREF101 and related docs for SandBox Apps for gain acces to USB port but, I dont find any help to my problen ... Can guideme about gain acces to the USB port...?  Any help will be apreciated.
