The USB interface contains four endpoints, which are defined as follows:
1. Endpoint 0 for the control transfer
2. Endpoint 1 IN for the Bulk transfer
3. Endpoint 1 OUT for the Bulk transfer
4. Endpoint 2 IN for the interrupt transfer
The Low-level API handles all Endpoint 0 (control endpoint) communications; thus PC driver enumeration
takes place during the device reset time and is transparent to an application. An application can be
written to monitor this reset signal to determine when it can start sending Endpoint 1 IN and/or Endpoint
2 IN packets to the host or to expect Endpoint 1 OUT packets from the host. (References to
transmission direction (IN/OUT) are relative to the host.)
USB_Init()
This function will activate the USB interface and ALL Endpoints will be ACTIVE. Endpoint 0 gets device
descriptor requests and will return the device descriptor. Endpoint 0 gets configuration descriptor

Purpose
Synopsis
Parameters
Return Codes None.
Configure the USB interface during the reset procedure. The descriptors (device,
configuration, endpoint, interface and string) used in future enumeration requests are
configured. When leaving this function, the USB interface is ready to answer any
enumeration request.

The Device, Config, CCID, Strings and LangID structures are described at the end of
this function description.
pUSB: Input parameter
Specifies the Device, Configuration, Endpoints, Interfaces and String Descriptors
defining the USB interface.
pLangID: Input parameter
Specifies the Language ID codes String Descriptor.
pRESET: Input parameter
Specifies a pointer to the function to call when RESET signaling has occurred on the
USB bus.
pSUSPEND: Input parameter
Specifies a pointer to the function to call when SUSPEND signaling has occurred on
the USB bus.
pRESUME: Input parameter
Specifies a pointer to the function to call when RESUME signaling has occurred on
the USB bus.
