Windows 10 pro sermouse issue

Copper Contributor

Hello there,


I have a mobo with i7 11th gen and 6 com ports for industrial purposes.

Sometimes when gps is plugged on the com ports mouse does crazy moves. This is happening because windows identifies com port as serial mouse. I have changed the start value for sermouse to 4 from 3 and also disabled the automatic driver updates from registry but windows still shows 'Microsoft serial mouse' or 'Microsoft ball point' on device manager.

Since you've already changed the Start value for Sermouse to 4, try installing a custom COM port driver that is compatible with your GPS device.
You can do this by going to the Device Manager, finding the "Microsoft Serial Mouse" device, and right-clicking on it. Select "Disable device" and then restart your computer.
The problem is that Windows is treating the COM port as a serial mouse, causing the mouse to behave erratically when the GPS device is connected. This is because Windows is using the serial mouse driver to communicate with the COM port.
