==============================================================================

* Finger Sensing Pad Intellimouse Mode(scrolling wheel, 4th and 5th buttons)

==============================================================================

A) MSID 4: Scrolling wheel mode plus Forward page(4th button) and Backward

   page (5th button)

@1. Set sample rate to 200;

@2. Set sample rate to 200;

@3. Set sample rate to 80;

@4. Issuing the "Get device ID" command (0xF2) and waits for the response;

@5. FSP will respond 0x04.
