Which of the following is an advantage that a USB mouse has over a PS/2 mouse?

USB devices can draw up to 500mA (USB 2.0) or more per port, which is typically more power consumption than the minimal current drawn by a PS/2 mouse.

Both USB and PS/2 mice are comparably portable physical peripherals; the interface type does not meaningfully affect the portability of the mouse itself.

USB was architected with hot-swap capability as a core design requirement, enabling the OS to automatically detect attachment or removal and load or unload the appropriate driver dynamically. PS/2 ports lack this capability and traditionally require the system to be powered off before a PS/2 device is connected or disconnected to avoid port damage or non-detection.

Neither USB nor PS/2 mice provide any inherent security advantage over each other, as security is not a differentiating characteristic between these two interface types.
