About Properties
MagneSafe V5 devices have a number of programmable configuration properties stored in non-volatile
memory. Most of the programmable properties pertain to data formats other than vendor-defined HID,
but some of the properties deal with the device regardless of format (for information about changing
formats and making format-specific properties visible, see
Property 0x10 - Interface Type
). These
properties can be configured at the factory or by an administrator using software tools supplied by
MagTek. Changing these configuration properties requires low-level communication with the device.
Details for communicating with the device to read or change programmable properties are provided in
