Beginning with Windows CE .NET 4.1 0, power-manageable devices can belong to varying device classes. These device classes consist of predefined classes, as well as custom device classes. Power Manager functions that accept device names can also accept class-qualified device names. For example, each of the following names is a valid device name:

  • COM1:
  • {A32942B7-920C-486b-B0E6-92A702A99B35}\COM1:
  • {98C5250D-C29A-4985-AE5F-AFE5367E5006}\CISCO1.
  • {8DD679CE-8AB4-43c8-A14A-EA4963FAA715}\DSK1:

If a class does not qualify a device name, the device is assumed to belong to the default device class. For example, the names COM1: and {A32942B7-920C-486b-B0E6-92A702A99B35}\COM1: are equivalent.
