1. Overview OTG devices use the ID pin in the plug to differentiate A/b device,id ground is known as A-device, the USB host,a-device at the time of the connection always provides power to the bus, the ID floating is called the B-device, the connection time of the USB Devices, the device's

I only read the notes written by Spec for half a day, but it is a bit messy. After debugging is completed, the idea is not very mature. I guess there are many components and there may be something wrong. You are welcome to make a brick and then correct them. 1. the OTG device uses the ID pin in the plug to distinguish a/B device. The ID grounding is called a-device, which is the USB

Working principle of USB OTGThe most important extension of the OTG supplemental specification for USB 2.0 is its more energy-efficient power management and the ability to allow devices to work in the form of host and peripherals. OTG has two types of devices: Dualrole devic

1 Introduction With the release of USB, USB has become a standard interface. Currently, USB supports three transmission modes: low speed (1.5 Mb/s), full speed (12 Mb/s), and fast (480 Mb/s: block Transmission, synchronous transmission, interrupted transmission, and control transmission. USB is flexible and convenient

1 IntroductionWith the publication of the USB2.0 version number, USB is becoming more and more popular and has become a standard interface. Today, USB supports three transmission rates: Low speed (1.5mb/s), Full speed (12mb/s) and Fast (480MB/S), four transport types: block transfer, synchronous transmission, interrupt transmission, and control transmission. USB

This is a creation in Article, where the information may have evolved or changed. ID ( Identification ) role Identification pin two x USB when the device interconnects, how to make two devices know: Who is the master control? Who is peripheral"periphery"? This actually uses the new PIN, which is appended with the fifth pin in the traditional 4-pin USB interface:ID to be the master of mutual vaccinationUS

A USB pin typically four lines, defined as follows:To support OTG features, the Mini/micro USB interface extends an ID pin (4th foot)A device-side ID foot is grounded, the initial state is host, such as PC and the OTG device support deviceb device-side ID foot is dangling, d

As an Android technology home, USB OTG is what you must understand, so-called USB OTG is you can use the phone or tablet to charge, and the computer to transfer data from the Micro USB interface to connect other USB peripherals, s

Recently, customers asked to use the MTK 6572 chip via USB OTG add support wired network card, I checked all the hooks and hooks all the site, there is no relevant discussion, see the MTK to the data, including FAQs, only said to support the USB OTG keyboard and mouse and USB
