Real solution to G4 GPS being detected by Windows as crazy serial mouse?
Has anyone else had their G4's GPS go haywire?
A few weeks ago, my GPS spontaneously started being detected by Windows as a serial mouse. The mouse goes around the screen extremely fast and clicking everywhere (causes massive mayhem and makes the system completely unusable). The problem even occurs during Windows XP/Vista setup (the only time it doesn't happen is Safe Mode). It happens even if nothing is plugged in, including the GPS antenna (no connections other than power). After finally figuring out that it was being detected as a serial mouse (by turning off COM ports in the BIOS), I found a number of supposed solutions on the Internet. None of them helped:
- Adding /noserialmice or /noserialmouse in c:\boot.ini (no effect).
- Disabling the "serial mouse" in the device manager (stops the spastic mouse, but the GPS is not detected by Streetdeck or Centrafuse).
- Disabling serial mouse detection by setting SkipEnumerations=FFFFFFFE in the registry under [HKLM\SYSTEM\CurrentControlSet\Enum\ACPI\PNP0501\Po rt#\Device Parameters] (stops the spastic mouse, but the GPS is not detected by Streetdeck or Centrafuse).
At this point I have just disabled COM1 in the BIOS, and of course have no GPS capability. I am planning on buying a USB GPS, but have several questions:
- Has anyone else had this problem with the G4? If so, did you find a real solution to keep using the integrated GPS?
- Is there any way to keep using my existing GPS antenna? I'm thinking of a device that would accept my GPS antenna and then plug into a USB port. It just seems like a waste to throw out my current GPS antenna (and maybe worse, to have to rewire the new antenna).
- If I have to buy a USB GPS, are there any recommendations?
