Otherwise setupapi may fail to find the device on which to set the
property. This triggers messages like the following the first time a
device is created (on prefix creation for mouse and keyboard devices):

  IoSetDevicePropertyData Failed to open device, error 0xe000020b.

Some IoSetDevicePropertyData implementation detail makes it always
return successfully but it's not doing anything and user32 will then
ignore the device when it enumerates rawinput devices.
