Indeed. We did exactly that a couple of years ago, bypassing the USB device hardware and achieving direct communication with an optical mouse's sensor chip. (We had some success in using that communication to track how much carpet was going by the sensor, as long as the height above the carpet was absolutely constant. The slightest variation -- a millimeter one way or the other -- changed the pixel-to-distance relationship, and threw off the tracking accuracy to the point where it was no longer useful. We gave up on the concept, but perhaps someone else can come up with a solution that we didn't think of.)
