Mouse driver update: input lifecycle reference
How pointing-device identity, reports, shared class support, and vendor extensions fit into a computer input stack.
Pointing identity has several layers
A mouse can be represented by a USB interface, Bluetooth connection, receiver, HID report descriptor, host device instance, and application pointer abstraction. A product name is useful for navigation, but each layer can carry a different identifier and lifecycle record.
Reports become pointer events
A pointing interface commonly reports relative movement, button state, wheel data, or device-defined controls. The transport and HID layers carry those fields; a host input class component turns them into events that applications can consume. The screen cursor is therefore not the same object as the hardware report.
Shared support and optional features
Standard pointing behavior can come from a shared input class component. Vendor software may add sensitivity profiles, lighting, macros, or configuration through additional interfaces and services. Those optional controls have a different package scope from basic pointer movement.
Version records need a named owner
A version may identify a receiver component, a HID-related package, a vendor service, or a bundle containing several pieces. Comparing a mouse version is meaningful only after identifying which layer owns the record and which interface it describes.
Physical and software boundaries
Battery state, a receiver, cable, sensor, pairing relationship, surface, and application settings can affect pointer behavior without changing a driver record. A neutral reference keeps those observations separate from package identity and platform input state.

Questions and answers
Does every mouse have a model-specific driver?
No. Many standard mice use shared class support; optional vendor controls may add separate software layers.
Is a cursor position a mouse-driver record?
No. The device can report movement while host input layers and applications maintain their own pointer and screen state.
Can a receiver and mouse have different identities?
Yes. The receiver, wireless device, HID interface, and package can each have distinct records in the input stack.
