Need Descriptor object for application use #3

A Descriptor (class name may change) ideally will be returned when a application requests a parsed HID descriptor. With that object, the application could, for example, read out mouse x,y values without manually decoding the bytes from their offsets

device = hidparser.parse(descriptor)

# After reading from hid endpoint
device.deserialise(received_data)
print("mouse pointer: {}".format(device.mouse.pointer)
# mouse pointer: (10, 54)

alternatively, using the DescriptorBuilder an application may create a Descriptor object or generate byte array to configure hardware with

The Device class provides access to reports (inputs, outputs and features) through instance named after their collection usages, i.e. Generic Desktop -> Mouse -> Pointer becomes device.mouse.pointer
