INTERFACE TYPE PROPERTY
Property ID: 16 (0x10)
Property Type: Byte
Length: 1 byte
Get Property: Yes
Set Property: Yes
Default Value: 0 (HID)
Description: The value is a byte that represents the devices interface type. The value can
be set to 0 for the HID interface or to 1 for the keyboard emulation interface.
When the value is set to 0 (HID) the device will behave as described in the
USB communications (HID) section of the manual. When the value is set to 1
(keyboard emulation) the device will behave as described in the USB
communications (KB) section of the manual. This property should be the first
property changed because it affects which other properties are available.
After this property is changed, the device should be power cycled before
changing any other properties.
This property is stored in non-volatile memory, so it will persist when the unit
is power cycled. When this property is changed, the unit must be reset (see
Command Number 2) or power cycled to have these changes take effect.
