USB Device HID Maximum Number of Instances 

This macro defines the number of instances of the HID Function Driver. For example, if the application needs to implement two instances of the HID Function Driver (to create composite device) on one USB Device, the macro should be set to 2. Note that implementing a USB Device that features multiple HID interfaces requires appropriate USB configuration descriptors.
