Connect EtherCAT Device with pysoem

I would like to communicate with an EtherCAT Device. Unfortunately, I can't even open the interface.

This is the Adapter as read out by the code provided:

Adapter 6\Device\NPF_{1F2BE908-A7E6-4622-BE1B-64E48F18FA6C}b'Intel(R) Ethernet Connection (11) I219-LM'

Actual Code:

import pysoemadapters = pysoem.find_adapters()for i, adapter in enumerate(adapters):   print('Adapter {}'.format(i))   print('  {}'.format(adapter.name))   print('  {}'.format(adapter.desc))master = pysoem.Master()master.open("/Device/NPF_{1F2BE908-A7E6-4622-BE1B-64E48F18FA6C}")if master.config_init() > 0:   for device in master.slaves:      print(f'Found Device {device.name}')else:   print('no device found')master.close()

Error:

could not open interface /Device/NPF_{1F2BE908-A7E6-4622-BE1B-64E48F18FA6C}
