Using a Win 10 system to access all connected devices using device manager and Py script

Question

I am unable to access the disk drives on the Windows system using infi.manager package found on PyPi.

Tried the below :

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

Error messages :

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.

During handling of the above exception, another exception occurred:

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

The above exception was the direct cause of the following exception:

Answer 1

from infi.devicemanager import DeviceManager
dm = DeviceManager()
dm.root.rescan()

devices = dm.all_devices
for device in devices:
    print(device)
