使用Win 10系统使用设备管理器和Py scrip访问所有连接的设备

Question

我无法使用PyPi上的infi.manager包访问Windows系统上的磁盘驱动器。你知道吗

尝试了以下操作：

  from infi.devicemanager import DeviceManager
  dm = DeviceManager()
  dm.root.rescan()
  disks = dm.disk_drives
  names = [disk.friendly_name for disk in disks]

错误消息：

Traceback (most recent call last):  
  File "C:\Users\rsushmit\AppData\Local\Programs\Python\Python37-32\lib\site-packages\infi\devicemanager\setupapi\functions.py", line 56, in callee

    raise WindowsException(GetLastError())
infi.devicemanager.setupapi.WindowsException: 259, No more data is available.

在处理上述异常时，发生了另一个异常：

Traceback (most recent call last):
  File "C:\Users\rsushmit\AppData\Local\Programs\Python\Python37-32\lib\site-packages\infi\devicemanager\setupapi\functions.py", line 60, in callee
    raise StopIteration
StopIteration

上述异常是以下异常的直接原因：
