USB Interface Adapter接到PC端指示灯不亮

之前检测EVM开发版一直工作正常，想试试固话程序，按照使用说明下载DATA FLash后，先断开

USB与PC端再断开与开发板端。在重新连接PC后，发现USB Interface Adapter的指示灯不亮了，而且显示没有安装驱动，不识别设备。

有没有什么建议。方便的话技术人员能不能加一下我微信解决一下renyanlin099960

    1.3 Step-by-Step Instructions for Operation and Troubleshooting
    List of Software Items for Operation
    In addition to the previously listed hardware items, the following software also is needed:
    • I
    2C/GPIO/PMBUS/SMBUS transport layer DLL driver (PMBus Transport (USB HID).dll) created by TI
    • Demo GUI software (USB SAA GUI.exe) for I
    2C/GPIO/PMBUS/SMBUS application
    Both can be downloaded from the TI website in the file "USB interface adapter GUI.zip", which also
    contains other accessory files.
    The USB interface adapter is recognized by a PC as a generic human interface device (HID), which is
    supported by the built-in USB/HID drivers of the Windows operating system. Therefore, it is plug and play
    and no proprietary USB driver is required.

    上边是sllu093的说明，意思是不需要驱动吗，是我的USB Interface Adapter硬件坏了吗

    z在设备管理器内查看是否有COM 口或者USB设备识别
