From: http://hyt19860117.love.blog.163.com/blog/static/127773729201042435553852/ With the improvement of people's living standards, more and more USB devices are used, but Linux still does not fully Plug and Play in hardware configuration. how to configure and use Linux is alsoThis article is intended to help you understand how to develop a USB driver to facilita

To do USB-related things in wince, we must first understand some concepts, which is very important. (1) host and FunctionFirst, you must know that the USB is a master-slave structure. For PCs and mobile phones, the PC end is the master end, called the host, and the mobile phone is the slave end, usually called the client. However, this term has changed in wince. The master end is also called host, while the

other half. On the contrary, whenever one structdevice_driver is born, it goes to the devices linked list of the bus to find its devices. If appropriate, call device_bind_driver to bind the device. If it cannot be found, it does not matter. wait. In fact, perfecting this triangular relationship is one of the important missions completed in each device driver initialization phase. Let's go back to the code. the usb_register function is called, but wha

I. Linux USB driver levels 1. devices, configurations, interfaces, and endpointsThe logical organization of a USB device consists of four layers: device, configuration, interface, and endpoint. A device usually has one or more configurations: Each USB device provides different levels of configuration information,

Hardware driver in Linux system-USB device (on) There are more and more USB devices, while Linux is still not completely plug-and-play in hardware configuration. how to configure and use Linux is becoming a major problem for us. This article describes how to use and configure the driver and how to compile the

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 d

Delphi sometimes cannot connect to debug some phones, solutions:1. Install Google USB Driver2. Check the phone or tablet USB vid,pid via Device Manager3. Modify the Android_winusb.inf on your computer to add the vid,pid found in the 2nd step to the INF.For example:; Samsung Galaxy S3%singleadbinterface% = usb_install, usb\vid_04e8pid_6860%compositeadbinterface% =

completed in each device driver initialization phase. Let's go back to the code. The usb_register function is called, but what is the parameter passed to it? We noticed that the code for calling the usb_register function is as follows: 1073/* registerthe driver, return usb_register return code if error */ 1074 retval = usb_register ( usb_storage_driver ); Yes, I passed a guy named usb_storage_driver. What

With the increasing number of USB devices, we have become more involved in driver development for USB devices. However, many beginners have the following three difficulties:First, we have little knowledge about the driver structure of wince and cannot focus on the development of the
