deviceinterface is a macOS process (listed here as Apple device interface daemon). People usually find it in Activity Monitor when asking “what is this process?”
What does deviceinterface do?
deviceinterfaced is the DeviceInterface framework daemon installed with Apple's Mobile Device software under /Library/Apple, next to usbmuxd. It arbitrates low-level transport channels to attached Apple devices and accessories — debug-USB, DockChannel serial, RSM channels, and the TADFU firmware-update transport — and exposes them to system clients through its device-interface Mach services. launchd starts it when matching Apple USB hardware attaches and keeps it available for device tooling such as restore and update workflows. Quitting while a device is connected can interrupt those sessions; launchd relaunches it on demand. The process name may truncate to deviceinterface.
