Describes the architecture of the USB function stack.

USB driver is crucial when you want to access your Android device from a Windows computer for file transfer, tethering, rooting, backup or Android data recovery.In most cases, Android USB driver should be automatically installed when you first connect your handset to a Windows 7/8/10 computer.

On a USB device, the USB function stack refers to a group of drivers that are enumerated by the Plug and Play Manager, when ACPI creates a USB device physical device object (PDO).

In a single configuration device, a USB device can define one or more interfaces. For example, the Media Transfer Protocol (MTP) for transferring files to and from the device. A composite USB device can support multiple interfaces in a single configuration. The USB function stack creates PDOs for each interface and PnP Manager loads the class driver that creates the function device object (FDO) for that interface.

The USB function stack is conceptualized in this image:

Applications and Services

All user-mode requests are sent to the Microsoft-provided kernel-mode class driver GenericUSBFn.sys. You can create a user-mode service that communicates with GenericUSBFn.sys by sending I/O control codes (IOCTLs) as defined in genericusbfnioctl.h. For more information about these IOCTLs see Communicating with GenericUSBFn.sys from a user-mode service

USB function class driver

A USB function class driver implements the functionality of a specific interface (or group of interfaces) on the USB device. MTP and IpOverUsb are examples of system-supplied class drivers. The class driver may be implemented purely as a kernel-mode driver, or it may be a user-mode service paired with the system-supplied class driver GenericUSBFn.sys.

A function class driver sends requests to the controller by using USB function class driver to UFX programming interfaces.

USB function class extension (UFX)

The USB function class extension (UFX) is a system-supplied extension to Kernel-Mode Driver Framework (KMDF). USB is a standard bus and has some required functionality and capabilities. UFX is responsible for implementing USB function logic that is common to all USB function controllers and handling and/or dispatching requests from USB function class drivers. In particular, UFX handles the process of enumerating the device and processing standard control transfers. To perform some of these operations, UFX needs to know about the capabilities of the bus. Those capabilities are reported to UFX when the class-extension interface is established.

UFX exposes standard IOCTLs that the upper layers (USB function class driver and user mode services) can use to send requests to the controller. Additionally, UFX notify upper layers about the standard requests received from the host.

USB function client driver

UFX provides an abstracted interface that works consistently across different controllers. However, controllers have different capabilities, with limitations such as the number of endpoints, the types of endpoints, low power, remote wake-up. For example, certain controllers support DMA, while others do not. Some controllers implement streams in the hardware while other controllers expect the driver to handle streams. For these reasons, only common functionality is handled in UFX. Transfers, power management, stream support, and other features which vary from controller to controller are handled by the client driver.

The USB function client driver is responsible for implementing controller-specific operations. These include implementing endpoint data transfers, USB device state changes (reset, suspend, resume), attach/detach detection, port/charger detection. The client driver is also responsible for handling power management, and PnP events.

The function client driver is written as Kernel-Mode Driver Framework (KMDF) driver by using USB function class driver to UFX programming interfaces.

Microsoft provides in-box function client drivers (UfxChipidea.sys, Ufxsynopsys.sys) for ChipIdea and Synopsys controllers.

USB lower filter driver

A USB lower filter driver supports detection of chargers if the function controller uses the in-box Synopsys and ChipIdea drivers. The filter driver manages USB charging starting from USB port detection. t must publish a GUID for each charger type it supports, and a list of that charger’s properties. If a specific charger is configurable, the lower USB filter driver defines a list of supported PropertyIDs and their corresponding value types that can be sent to it, to configure the charger. The driver also notifies the battery stack when it can begin charging and the maximum amount of current the device can draw. For client drivers other than Synopsys and ChipIdea drivers, charging logic can be implemented in the client driver.

A function class driver sends request to UFX by using Programming interfaces for supporting proprietary chargers.

What is ADB and Fastboot?

These are the tools that are used to send terminal commands to an Android device from a command line on a PC. Besides, when your phone is connected with active USB debugging, you can issue commands and communicate with the phone using your computer.

Moreover, it generally works when an Android phone is switched on and booted into recovery. Whereas Fastboot is a tool that works in bootloader mode and allows you to re-flash system partitions on Android phones.

Most importantly, the installation of 15 sec ADB installer is quite easy. All you have to do is extract the setup file on your PC. Then open the tool and follow the given step by step instructions.

Moreover, this is an all in one ADB installer which successfully installs the latest ADB drivers, fast boot drivers, and Google USB drivers. The actual size of this ADB installer is just 9 MB. However, it still supports all variants of Android smartphones and tablets.

Changelog

Updated ADB and fast boot to API 23 version
Updated Google USB Driver
