Windows 7 & GPS


  • How to prevent Windows 7 to falsely detect serial GPS as serial mouse?

    Each time we start windows with a serial GPS connected, it thinks it's a mouse.

    We try the same method we used on Win XP to correct the problem & it did not work.

  • Hi Jacques_St-Pierre,

    I would suggest you to download the GPS device driver and check if issue gets fixed.

    Use Windows Update

    1. Open Windows Update by clicking the Start button . In the search box, type Update, and then, in the list of results, click Windows Update.?

    2. In the left pane, click Check for updates.

    If there are any available updates, click the links to see more information about each update. Windows Update tells you if an update is important, recommended, or optional. Each type of update might include drivers. For more information, see Understanding Windows automatic updating.

    3. On the Select the updates you want to install page, look for updates for your hardware devices, select the check box for each driver that you want to install, and then click OK.

    There might not be any available driver updates.

    4. On the Windows Update page, click Install updates.  If you're prompted for an administrator password or confirmation, type the password or provide confirmation..

    Windows Update will tell you if the updates were successfully installed.

    If you have model number you can contact the manufacturer for the compatible drivers with windows 7.

    If the drivers are compatible then I recommend you to update the drivers and see if it makes any difference. You must be logged on as an administrator to perform these steps.

    1. Open Device Manager by clicking the Start button, clicking Control Panel, clicking System and Maintenance, and then clicking Device Manager. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.

    2. In Device Manager, locate the Device, and then double-click the device name.

    3. Click the Driver tab, and then click Update Driver and follow the instructions.

    Try to follow the below provided link to Update a driver for hardware that isn't working properly and check for the issue.

  • The problem does not relate to drivers problems.

    No Drivers are available for our OEM GPS. No drivers are required for that kind of device.

    The problem is the same for any of our scientific instruments that send information via serial port (and yes serial port still used in real life).

    The problem lied in Windows, who stupidly think anything coming from a serial port at boot time is automatically from a mouse or a pointing device.

    What we need is a way to disable the detection of pointing device (mouse or anything else) on any serial port when Windows 7 boot.

    We did have a way on Win 2000 & XP, but thoses solutions do appear to work on Win 7.

    Refer to Article ID # 283063 & 833721 ( /fastdetect or /noserialmice )

    If Microsoft can not provide a way to correct Win 7, we will have to downgrade all our scientific used computers to XP and advice our IT to stop buying Win 7.
