In order to protect mobile devices in the computer can be normal operation, the first access to a computer need to install a driver, mobile phone needs to install mobile drive, u disk need to install USB drive and so on. When you connect a USB drive or mobile device such as a mobile phone to your computer, you will find that "installing the driver" appears in the lower-right corner of your computer's toolb

With the increasing of USB devices, development of USB driver is becoming more and more important in embedded development. Windows CE's support for USB 2.0 is a huge boost to this wave of new technologies. The author of this article analyzes his own use-driven development experience, hoping that readers can take less detours. With the increasing of

In modern embedded systems, asynchronous serial communication interfaces are usually used as standard peripherals in single-chip microcomputer and embedded systems. However, as the general peripheral devices of personal computers use less and less serial ports, serial ports are gradually disappearing from personal computers, especially portable computers. As a result, embedded developers often find that their new computers do not have serial ports, or there is an embarrassing situation where the

From, the Mobile storage market began to drop prices. Up to now, the price of large-capacity USB flash drives has been reduced to an unimaginable level, and even the price of 8 GB products has reached 300 yuan. However, although the capacity has gone up, the general USB flash drive features have not changed and extended much, which is a pity. Today, we will introduce a method to enable common

Enumeration is to read some information from the device, know what device it is, how to communicate, so that the host can be based on this information to load the appropriate driver.To debug a USB device, it is important that the USB enumeration process, as long as the enumeration succeeds, then it is half the s

The reason why I first wanted to learn about USB was that I wanted to have a universal programmer very much at the time. Although the commercial programmer had good functions, it was expensive, it seems a pity to buy one just for programming several chips (I have already bought the programmer :)). So I want to make a simple one by myself, using serial ports? Parallel? I don't like the idea of adding a big, stupid external power source. It's good to us

USB urb (USB request block) Kernel 2.6.29.4The USB device driver code communicates with all USB devices through urb. Urb uses the struct urb structure description (include/Linux/USB. h ). Urb sends or receives data asynchronously from a specific endpoint of the same

Quick USB Learning (Single Chip Microcomputer Application)(Prepared by flashman, qq28479691. If you want to reprint it, please specify the source) USBI believe everyone knows the advantages of this technology, and it is still very profitable. Hey hey, let's not talk about it here. If you don't understand it, go and read the book. Here we will talk about how to quickly master the USB technology. In this arti

Important key words for USB:1, endpoint: A data buffer located on the USB device or host, used to store and send various USB data, each endpoint has a unique address, there are different transmission characteristics (such as input endpoint, output endpoint, configuration endpoint, bulk transfer endpoint)2, Frame: Time concept, in the

Writing a simple USB DriverFrom Issue #120April 2004APR, 2004 by Greg Kroah-hartman in Software Give your Linux box A multicolored light can see from across the class, and learn how to write a simple driver for the Next piece of hardware you want to hooks up.Since This column began, it had discussed how a Linux driver writer can create various types of kernel drivers, by explain ing the different kernel driver interfaces including TTY, s

How to set up USB for Virtualbox? USB in different versions of Virtual BoxFor use of the USB in Virtual Box 3.x need a puel-version. From Virtual Box > 4.x USB 1.0 are supported in the OSE version installed from Software Center. For USB 2.0 or

one, Linux under the USB driver Separation and tiering is the most basic form of driver development in Linux, USB drive development in the host side mainly involved in two parts: Host controller driver and device driver. Host controller driver is mainly related to the specific SOC, it is to identify the USB device, install the corresponding device driver, to prov

Here we mainly talk about the overall structure of the USB driver protocol stack in Windows XP and some important internal data structures. When writing these things, I referred to the related forum posts of Daniel Tiamo. The content is similar and I can't say that it is a repost. The USB protocol stack consists of the following driver files: the USB port. sys

All drivers in winceare loaded by the device.exe process in the form of dll. therefore, the dllentry function must be implemented in each driver. The driver information of the USB host is saved under the HKEY_LOCAL_MACHINE \ drivers \ USB \ loadclients \ key in the registry. The first time we inserted a USB device. Because this information does not exist, a"Unrec

Important USB keywords: 1. endpoint: a data buffer zone located on a USB device or host. It is used to store and send various USB data. Each endpoint has a unique fixed address, has different transmission features (such as input, output, configuration, and batch transmission) 2. frame: the concept of time. In USB,
