Functions

func ParseIDs

func ParseIDs(r io.Reader) (map[ID]*Vendor, map[ClassCode]*Class, error)

ParseIDs parses and returns mappings from the given reader. In general, this should not be necessary, as a set of mappings is already embedded in the library. If a new or specialized file is obtained, this can be used to retrieve the mappings, which can be stored in the global Vendors and Classes map.

Types

type Class

type Class struct {
	Name     string
	SubClass map[ClassCode]*SubClass
}

A Class contains the name of the class and mappings for each subclass.

func (Class) String

func (c Class) String() string

String returns the name of the class.

type ClassCode

type ClassCode uint8

ClassCode represents a USB-IF (Implementers Forum) class or subclass code.
