The operating system will automatically detect and enable common USB input devices when they are connected.
Device features (macro buttons, 3+ buttons, notifications) that rely on middleware drivers or enabling applications may have limited functionality until those services are installed and operational. Thus, it is recommended to use basic devices for initial development work.
|Note: USB hardware ports provide a limited amount of current per their specification. It is recommended to use a powered USB hub with input devices that have features like backlights, precision optical sensors or when other devices like storage drives, trackballs or touch pads are also connected to the same device port.|
