One of these is the official Microsoft-launched WIA interface call scanner, which is currently up-to-date. In fact, this way is easy to write,But it does not store information such as the resolution the user needs to scan, but this method is easy and quick to install the WIA control toWindows, written directly in C # code, can be called directly, without having to edit the control's properties and so on, it is easy to use.Another way is the traditional Twian, because many scanner manufacturers a

Control program.In addition, routing and address resolution are handled by the kernel.
Loadable Modules
The features provided by the Linux kernel can be extended at run time, that is, when the system is up and running, we can add or remove functionality from the kernel to the kernel.Code that can be added to the kernel at run time is called a "module."The Linux kernel supports several types of modules, including but not limited to device drivers.Each module consists of target code
How to use the device tree of linux drivers and how to use the device tree of linux drivers
The Device Tree describes the hardware from the software perspective, and DTS is the Device Tree source file. DTC is responsible for converting DTS to DTB, and DTB is the binary form of DTS for machine use.
The Device Tree is a tree structure. Each child node except the root node has a unique parent node, which can h
This is a 2014kdd, geographic location service paper.

1) First, the author raised a valuable Question: recommend taxi drivers with routes that can be carried to the guests at the minimum cost.
2) Secondly, the novelty of the problem is that in the past, there were scattered recommendation points. This paper is a recommendation route. It can be said that the location service provided goes further.
3) then, two sub-problems are pointed out: a)
The stream device driver is actually the driver for exporting standard stream interface functions. This is the definition above. In wince, all stream devices export stream device interfaces, so that Device Manager in wince can load and manage these stream device drivers.

Poll for linux drivers and poll for linux driversPOLL operations
1. POLL execution process:
Poll is a system call. Its kernel entry function is sys_poll. sys_poll calls do_sys_poll directly without any processing. The execution process of do_sys_poll can be divided into three parts:
1. Copy the input pollfd array to the kernel space. Because the copy operation is related to the array length, this is an O (n) operation, in do_sys_poll, the code in this
This document describes how to use ctl_code to communicate with a Windows NT driver. generally, user-Mode Applications can communicate with kernel-mode drivers by calling createfile and deviceiocontrol, if a driver in the kernel state wants to perform similar operations with another driver, how can this problem be achieved? Next, we will provide a detailed description.
The main idea is to first get the handle of another driver, then construct an IRP,

Under Windows 9x, drivers can be divided into sound card drivers, graphics drivers, mouse drivers, motherboard drivers, network device drivers, printer drivers, scanner
TIPS:1. please install the driver in sequence. The downloaded driver is an executable file, but it is not installed only when the file is released. By default, it is released to C: in the/Drivers/win/*** directory, go to the file directory to continue the installation.2. before installing WINXP, you need to change the hard disk to compatible mode in the BIOS. Otherwise, the system will prompt that the hard disk or blue screen cannot be found during in
