　调制解调器是一种使计算机通过电话线路通信的设备。使用调制解调器，您可以向另一台配有调制解调器的计算机发送数据。这使您可以从全球网 (World Wide Web) (正如您现在所做的一样) 中下载信息、发送和接收电子邮件 (e-mail) 及与远程对手玩计算机游戏。一些调制解调器还能发送和接收传真及语音电话呼叫。 　　不同的调制解调器通信速率也不相同。许多新型的调制解调器能以 33.6 kbps 的速率发送和接收数据；以 14.4 kbps 的速率发送和接收传真。一些调制解调器能以高达 56 kbps 的速率从 Internet 服务供应商处 (ISP) 下载信息。 -modem is a type of computer through the phone line communication equipment. Use a modem, you can to another modem equipped with a computer sent the data. This allows you to a global network (World Wide Web) (as you are doing the same), download information , sending and receiving electronic mail (e-mail), and long-distance rivals playing computer games. Some modems can send and receive fax and voice telephone call. Different modem communication speed are not identical. Many new modems able to 33.6 kbps rate of sending and receiving data; to the rate of 14.4 kbps sending and receiving fax. Some modems can be up to 56 kbps rate from the Internet service provider (ISP) Download information.

所谓固件，就是存储在程序内存中的程序,用以完成驱动程序无法完成的USB 芯片及外围芯片的初始化及控制工作[23]。USB固件程序设计是USB接口部分的主要工作，它的主要目的是：当USB设备连接到主机上时，主机可以发现新设备，然后建立连接并完成数据传输任务，也就是能够让Windows正常检测和识别USB设备。因此在USB固件程序中，最重要的工作就是USB描述符的定义和USB传输中断的处理。-called firmware is stored in the memory of the procedure, Drivers used to complete the impossible chip and external USB chip initialization and control work [23]. USB firmware design is USB major part of the work, its main objectives are : When USB devices connected to the host, the host can be found in new equipment, then establish a connection and data transmission to complete tasks, is to let the normal Windows USB detection and identification equipment. Therefore USB firmware procedures, the most important work is described USB define and USB transmission interruption of treatment.
