    USB Enumeration is the process of detecting, identifying and loading drivers for a USB device. This involves a mixture of hardware techniques for detecting something is present and software to identify what has been connected. The purpose of this document is to provide an overview of the mechanics of the process.
    The USB controller submits data to the host during the enumeration process to accomplish USB enumeration. The format of the enumeration data table for each USB controller is not necessarily the same. Some tables are designed using the C language, and others are designed using assembly languages. Most USB IC companies provide sample codes.
    High-Speed devices start as Full-Speed devices, so they have a 1.5-kΩ pull-up on the D+ line. When the device is connected, it emits a sequence of J-States and K-States during the reset phase of enumeration. If the hub supports High-Speed, then the pull-up resistor is removed. The pull-up resistor is essential to USB enumeration.
    In this post I will provide a detailed description of the enumeration process used by the Windows 7 core USB driver stack - from the point the stack detects a presence of device to the point it indicates to the PnP manager that a new device has arrived.
