Universal serial bus devices

A digital camera connected to your computer that enables you to send live pictures over Internet. Some webcams are wireless, while others are plugged into computers through USB ports. It is possible for a single USB cable to have both connectors.

A micro or mini USB cable would have two ends — male and female. The former is the end of a USB cable inserted in MP3 players, cameras and other peripheral devices, the latter is what you see on your computer. You can see it at the end of charger or data cable connected to your camera or mobile phone. Have a look at it and you will see it has five pins, while a standard USB has four of them. Mini USB typically either send or receive data, i. They are also used a charger connector.

Micro USB is even thinner than mini USB, it could be a data cable, charger or connector for digital cameras and mobile devices.

They are adopted for female USB ports of cameras and mobiles, have five pins and all of them are in operative mode. That is why micro USB cables can work in smartphones and tablets. The data can travel both ways at the same time. FlexiHub Team uses cookies to personalize your experience on our website.

Write a filter driver that supports detection of chargers, if the function controller uses the in-box Synopsys and ChipIdea drivers. The client driver handles hardware operations and events, power management, and PnP events. If you are developing an xHCI host controller that is not compliant with the specification or developing a custom non-xHCI hardware such as a virtual host controller , you can write a host controller driver that communicates with the UCX class extension.

Universal Serial Bus USB provides an expandable, hot-pluggable Plug and Play serial interface that ensures a standard, low-cost connection for peripheral devices such as keyboards, mice, joysticks, printers, scanners, storage devices, modems, and video conferencing cameras. Windows operating systems include native support for USB host controllers, hubs, and devices and systems that comply with the official USB specification.

Windows also provides programming interfaces that you can use to develop device drivers and applications that communicate with a USB device. Windows defines MS OS descriptors that allows better enumeration when connected to system running Windows operating system.

Windows provides in-box device class drivers for many USB-IF approved device classes, audio, mass storage, and so on. Windows provides Winusb. Parent driver for USB devices with multiple functions. Usbccgp creates physical device objects PDOs for each of those functions.

Get information about the tools that you can use to test your USB hardware or software, capture traces of operations and other system events, and observe how the USB driver stack responds to a request sent by a client driver or an application.

Read an overview of tests in the Hardware Certification Kit that enable hardware vendors and device manufacturers to prepare their USB devices and host controllers for Windows Hardware Certification submission. A useful resource for USB client driver developers and USB hardware designers understand the driver stack implementation, resolve common issues, and explain how to use tools for gathering traces and log files.

Discussion list managed by OSR Online for kernel-mode driver developers. Miscellaneous resources based on frequently asked questions from developers who are new to developing USB devices and drivers that work with Windows operating systems.
