That's a Linux-style device name. Other operating systems have different naming conventions.

The naming conventions on Windows, with WinPcap or Npcap, are... difficult. The names include a hex representation of a 128-bit GUID.

You should try using FindAllDevs to get a list of devices and show devices with both their names and descriptions, although the description may not be all that helpful.
