I have the "Sentinel Advance" (SGM-6000-KLLW1-GP) Mouse and it stopped working due to unknown reasons.
First, it is not recognized as USB device, not even in Safe-Mode. Not detected by app, "NO MOUSE" error; drivers re-install not work. Tried several methods via device manager but all of them failed.
All I can see is the LEDs constantly ON but instead of one, all 3 colors are powered. In the meanwhile I wanted to Re-solder the chip and the oscillator to see if there's any change, but never did, since I will be waiting for further instruction.
All I can hope is that there's software-ish malfunction.
