    It looks like there is something wrong on your Desktop USB port. Do you use a USB hub or connect lots of USB device on the Desktop? If so, try not to use USB hub or connect many other USB device at the same time. By the way, reboot Desktop might be helpful.

    That is my confused ! Any launchpads work in this desktop a few days ago, and other USB devices also normal in that desktop now, and I just connect the USB keyboard and mouse to desktop.

    Are there any other tools for checking the XDS110 ?

    regard.
