Abstract

A computer pointing device (65) has a coupling device (1) for coupling to a computer serial bus. A primary control device (60) is coupled to the coupling device (1). A computer pointing mechanism (62) is coupled to the primary control device (60) and a data storage device (10) is coupled to the primary control device (60). The primary control device (60) controls data flow between the coupling device (1) and each of the computer pointing mechanism (62) and the data storage device (10). The data storage device (10) includes an interface device (2) coupled to the primary control device (60), a memory control device (3) and a non-volatile solid-state memory device (4). The memory control device (3) being coupled between the interface device (2) and the memory device (4) to control the flow of data from the memory device (4) to the interface device (2).

Claims

1. A computer pointing device comprising a coupling device for coupling to a computer serial bus, a primary control device coupled to the coupling device, a computer pointing mechanism coupled to the primary control device and a data storage device coupled directly to the primary control device, the primary control device controlling data flow between the coupling device and each of the computer pointing mechanism and the data storage device;

the data storage device comprising an interface device coupled to the primary control device, a memory control device and a non-volatile solid-state memory device, the memory control device being coupled between the interface device and the memory device to control the flow of data from the memory device to the interface device.

2. A device according to claim 1, wherein the data storage device is located wholly within a housing of the computer pointing device.

3. A device according to claim 1 or claim 2, wherein the data storage device is not removable from the computer pointing device.

4. A device according to any of the preceding claims, wherein the data storage device receives and outputs data in the same format as the computer serial bus to which the computer pointing device is to be coupled.

5. A device according to any of the preceding claims, wherein the computer pointing mechanism is a computer mouse mechanism.

6. A device according to any of the preceding claims, wherein the non-volatile solid-state memory device is a read/write memory device.

7. A device according to claim 6, wherein the read/write memory device is a flash memory device.

8. A device according to claim 6 or claim 7, wherein the memory control device controls the flow of data to and from the memory device.

9. A device according to any of claims 6 to 8, further comprising a manually operated switch movable between a first position in which writing of data to the memory device is enabled, and a second position in which writing of data to the memory device is prevented.

10. A device according to any of the preceding claims, wherein the memory control device comprises a micro-controller.

11. A device according to any of the preceding claims, wherein the coupling device comprises a universal serial bus (USB) coupling device and the interface device comprises a USB driver.
