BlueNRGX闪光器实用程序无法识别SWD连接（STlink/V2）

Question

连接ST link/V2时，BlueNRG-X闪光器实用程序无法识别SWD连接。我正在通过命令行界面运行闪光器以获取错误消息（BlueNRG-X_flasher_Launcher.exe）。出现的错误消息是：

"Traceback (most recent call last):
  File "Script_launcher.py", line 542, in <module>
  File "globals.py", line 555, in get_stlink_list
  File "build\bdist.win32\egg\usb\core.py", line 1246, in device_iter

usb.core.USBError: [Errno 19] No such device (it may have been disconnected)
[47128] Failed to execute script Script_launcher"

似乎找不到一些python后端文件。我将libusb-1.0.dll复制到windows\system32并添加到path，但它没有解决问题
