PIC USB Interface

• The USB spec defines certain abstract types that every USB device must understand.

• “Endpoints” are a bit like sockets in the TCP/IP world. Endpoints are individually addressable sources and destinations for data. Many devices have several endpoints.

• The “interface” type describes a group of endpoints. Most devices have one interface.

• The “configuration” type describes various configurations the device may use. Most devices have one configuration.

• The “device” type describes the overall device and includes information such as manufacturer, product name, and serial number.
