Usbutil — For Mac

sudo usbutil reset-port 0x14130000 Note: This requires sudo and must be used carefully; resetting the wrong port can disrupt keyboard/mouse input. On laptops, you can query or toggle power to individual USB ports (e.g., to conserve battery or force a hard reset). Example:

usbutil power status usbutil power off 0x14130000 For everyday tasks—ejecting drives, viewing basic USB device lists, or checking transfer speeds— usbutil is overkill and potentially dangerous. Use diskutil list , system_profiler SPUSBDataType , or the Disk Utility app instead. sudo usbutil reset-port 0x14130000 Note: This requires sudo

system_profiler SPUSBDataType | grep -E "Product ID:|Vendor ID:|Speed:" This is safer, more readable, and fully supported across all macOS versions. usbutil is a surgical tool for the USB stack on macOS—not a general-purpose utility. It shines in debugging scenarios: a drive that won't mount, a device that vanished after sleep, or a hub that needs port-level reset. For developers and advanced administrators, mastering usbutil opens a window into the low-level USB architecture that graphical tools cannot provide. For everyone else, admire it from a distance, and stick with system_profiler . Ventura)
