The PS2USB Browser Combo Mouse is a type of mouse that typically works with both PS/2 and USB connections, often marketed as a "combo" device. It can be connected to a computer via either a PS/2 port or a USB port, making it compatible with various systems. The term "PS2USB" suggests the device is capable of being used with either connection type, and the "Browser" aspect may refer to special functions or buttons related to web browsing, like forward, back, or other programmable buttons.

In most cases, a Windows driver for this device would be necessary to ensure full functionality, especially for custom buttons and scrolling features. However, in many instances, basic mouse functionality (such as moving the cursor and clicking) is supported natively by Windows without requiring additional drivers. Custom features (like additional buttons) may require specific drivers or software.
