### Find a Mouse to Emulate

1. Go to [**http://www.linux-usb.org/usb.ids**](http://www.linux-usb.org/usb.ids).
2. Browse the list to find the mouse you want your KM Box to mimic.
3. Note down its **Product ID (PID)** and **Vendor ID (VID)** for later use.

### Prepare the KM Box Script

1. Connect your **KM Box** to your **second PC**.
2. Download and run [**`upycraft.exe`**](https://randomnerdtutorials.com/install-upycraft-ide-windows-pc-instructions/).
   * If a **"Font"** message appears, ignore it and proceed by clicking **Board** or **Serial** under the **Tools** menu.
3. In the script:
   * Locate the **dynamic PID and VID** command lines and `device.enable(1)`.
   * Remove the `#` from the start of these three lines.
   * *(See Picture #1 for before, and Picture #2 for after)*.
   * \#1

### Set Static PID & VID

3. Remove the `#` comment symbol if present.
   {% endstep %}

### Save & Upload the Script

### Reboot the KM Box

1. Unplug both **blue USB cables** to power down the KM Box until the screen turns off.
2. Plug them back in.
3. Your main PC should now detect a **new mouse** and begin installing it, along with the updated **VID/PID**.
