And did you install all the hardware drivers and enable the new device?

| The laser mouse discussed here, operates at 842nm. One article I checked,
| said the human eye can see to 780nm, so the laser mouse would be infrared.

| You can use a CCTV camera, web camera, or other camera with a silicon
| sensor, to see out into the infrared. For example, with my CCTV
| camera, I can see the pulses coming from an infrared TV remote
| control. So you can check for light, if you have a continuously
| operating camera of some sort. (Color cameras based on silicon, sometimes
| contain a filter that attenuates infrared light. A monochrome camera may
| lack this filter, and make an even better detector than a color camera.
| Some day/night CCTV devices, can actually remove the filter when changing
| from day to night mode.)
|
| There are also detector strips, that will detect infrared light.
| Radio Shack used to sell one. You "charged" the strip, by holding it
| near a light bulb for a few minutes. Then, in a darkened room, you
| could shine a suspected IR source on the strip, and it would emit
| visible light in response. More examples here:

| This paragraph, describes how the laser mouse works.
|
| "New Laser Mouse Principle
|
| The laser light is a kind of "Coherent Light" which is nearly a
| singular wavelength. Unlike the LED optical mouse, the laser tracking
| technology is capable of capturing the "Speckle Pattern Interferometry"
| from the laser light reflection. The images that laser sensor received
| are much more detailed and have higher contrast. Thus, the sensor can
| precisely analyze the continuous Speckel Pattern images and determine
| the cursor direction. Hence, the laser can track reliably even on
| irregularities pattern surface and reflect interference surface."
|
| Like ordinary mice, it is possible when the mouse is lifted up, that
| the source response will be different. As part of remaining eye safe,
| the laser may not operate continuously, if the sensor detects a lack
| of reflections. So holding it up, in fact, could modify the operating
| mode of the laser.
|
| Does the mouse have batteries installed ?
| Are the batteries known good ?
| Is there a slide switch on the mouse, to enable it ?
| If the mouse is rechargeable, did you put it in the recharger stand for
| 24 hours, to apply an initial charge ? Some devices need to be charged
| before being used.
