How To Disable The Serial Mouse Driver In Windows 7 and Windows 10


On JetStream products, an embedded PC uses a serial port to connect to the DSP card for administration.
On AE-32 products, an external PC uses a serial port to connect to the DSP card for administration.

Windows will see the metering data we send on the serial port and think it's a serial mouse and load the serial mouse driver. That prevents our software from being able to properly load and communicate with the DSP card.


Here is how to force Windows to not load the serial mouse driver on boot in Windows 7 and Windows 10:

  1. Click the Start button, type “regedit” in the Search field, and then open the Registry Editor.
  2. Navigate to the registry key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\sermouse
  3. In the right pane of the Registry Editor, select Start and change its value to 4 to disable serial mouse detection at boot time.
  4. Close the Registry Edior and restart your PC.
We make this edit to the registry before we ship JetStream products, but some Windows updates will reset the Start value, meaning you need to set it again.

The reboot at the end is mandatory.
