USBAppControlServer
USBAppControlServer is a utility component from Brother Industries that manages USB communication between Brother printers, scanners and other peripheral devices and the main Brother driver software on macOS. It enables device detection, firmware updates, and feature control for Brother hardware through a USB connection. Most users encounter this app bundled automatically when installing Brother printer or scanner drivers, and it typically runs in the background to maintain device connectivity.
AI Recommendation
1 suggestionBased on the bundle ID com.brother.utility.USBAppControlServer, this is a helper component of Brother's printer/scanner driver suite rather than a standalone application. Helper utilities like this are not separately updatable — updating the parent Brother driver software is what brings the helper component up to date and ensures it is compatible with your Mac's architecture. Check Brother's support website for your specific device model (printer or scanner) and download the latest macOS driver. Brother has been shipping native Apple Silicon support in their modern drivers, so updating the parent driver should resolve this component's Intel-only status. If you are unsure which Brother device you have or which driver to install, visit brother.com/support, enter your model number, and download the latest macOS driver for your system.
