host, only one device can communicate with the host at the same time. Manage the external USB device via the USB host controller. USB controller is actually composed of USB controller hardware +USB Controller software. The USB host controller is divided into 3 kinds: UHCI, OHCI, EHCI. UHCI and OHCI Support USB1.1 protocol; EHCI supports USB2.0 protocol. UHCI, its hardware is simple, so the software is relatively complex, and OHCI, its hardware has more performance, contrary to the software to

This section describes the Linux Device Driver framework, driver configuration files, and common methods for loading drivers. It also describes how Red Hat Linux installer loads drivers, we can put the driver into the boot disk by ourselves; after installing the system, we can use kudzu to automatically configure the hardware program. 　　Linux Device

1. Device Driver. In the Linux device model, the device driver is represented by the device_driver structure. Struct device_driver {const char * Name;/* name */struct bus_type * bus;/* attached bus */struct module * owner; const struct of_device_id * of_match_table; INT (* probe) (struct device * Dev);/* call */INT (* remove) (struct device * Dev) when the device matches the

You know, drive life. Network card version of the new Realtek network card driver win10 version? Often heard that a small partner said that after the installation of the WIN10 system, the computer can not network. Even in the use of Driver Life Card version to install the network card driver is still unable to solve the problem. Because the WIN10 system can use

Access to the character device is performed through the device name in the file system. Those device names are simply nodes that are called file system trees, and they are typically located in the/dev directory. Device files for character device drivers can be identified by ' C ' in the first column of the ls-l command output. Block devices are also located in/dev, identified by the character ' B 'CRW-RW----1 root root 253, 0 2013-09-11 20:33 Usbmon0CRW-RW----1 root root 253, 1 2013-09-11 20:33

Using drivers:1, character device : Refers to a byte can only one byte read and write devices, can not randomly read the device memory of a certain data, read data need to follow the data. The character device is a stream-oriented device, and the common character devices are mouse, keyboard, serial port, console a

Linux under the I2C-driven loading process, divided into I2C equipment layer, I2C adapter layer and I2C core layer The I2C device driver layer is the drive we write for a particular I2C device, and the following is the I2C-driven registration process I understand. In the I2C device driver we write, we call I2c_add_driver () to start I2C device-driven registration, which calls I2c_register_driver Complete a

1. Overviewin general, the 2.6 kernel has been initialized and mounted with a platform bus in the Sysfs file system. So when we write the platform model driver, we need to do two jobs:1: Implement platform Drive 2: Implement PLATForm Device, however There are many other small tasks that need to be implemented in the process of implementing these two tasks, as described later. The core architecture of the platform model-driven implementation process
