	// Indicates whether the item creates variable or array data fields in reports
	//   Variable: For example, a bank of eight on/off switches could be reported in 1 byte declared by a variable Input item where each bit represents one switch, on (1) or off (0) (Report Size = 1, Report Count = 8).
	//   Array: A keyboard could report up to three simultaneous keys using an array with three 8-bit fields (Report Size = 8, Report Count = 3).Logical Minimum specifies the lowest index value returned by the array and Logical Maximum specifies the largest. The number of elements in the array can be deduced by examining the difference between Logical Minimum and Logical Maximum (number of elements = Logical Maximum - Logical Minimum + 1)

	IsLinear                      bool // Nonlinear indicates whether the raw data from the device has been processed in some way, and no longer represents a linear relationship between what is measured and the data that is reported
	IsRange                       bool // Specifies, if TRUE, that the structure describes a usage range. Otherwise, if IsRange is FALSE, the structure describes a single usage
	IsVolatile                    bool // Indicates whether the Feature or Output control's value should be changed by the host or not. Volatile output can change with or without host interaction
	HasNull                       bool // Indicates whether the control has a state in which it is not sending meaningful data
	HasPreferredState             bool // Indicates whether the control has a preferred state to which it will return when the user is not physically interacting with the control
	Wrap                          bool // Indicates whether the data “rolls over” when reaching either the extreme high or low value
