Remove USE_NONSTANDARD_DESCRIPTOR_NAMES compile time token, split out standard descriptors into seperate USB_Descriptor_* and USB_StdDescriptor_* structures so that both can be used within the one project.
Add guard to the HID Host Class driver SetProtocol command, to ensure that the device supports boot protocol mode before issuing the request.
