Hello Jiyuan,
It's not clear how they are connecting the mouse, but they need to connect it to the left-hand USB port next to the zero-ohm resistors while turning the switch to DEVICE.
I don't see any indicator that is what they have done after setting up the hardware correctly on the LaunchPad.
I saw they did that previously but now that the board modification are done, it is very important to switch to DEVICE so that the USB circuitry isn't connecting to the ICDI but instead directly to the target device USB.

Hi support team,
Could you please provide a video demonstration of the working mouse cursor and board modification that you mentioned in your USB post? We tried several times, but it still does not work for us.
Here are most recent modification video: youtube.com/.../03hmHJdgS2I
thank you!
Hello Jiyuan,
It looks like the demo isn't well understood. The mouse won't move the screen, that is not how the demo is configured.
You need to open a terminal window that connects to the Stellaris Virtual Serial port and then when the mouse is moved it should report on the current position of the mouse in the terminal window.
//! This application demonstrates the handling of a USB mouse attached to the //! evaluation kit. Once attached, the position of the mouse pointer and the //! state of the mouse buttons are output to the UART terminal.
Best Regards,
