在我們的資訊生活中USB裝置一直被廣泛運用，對嵌入式系統的發展人員而言，依研究方向，有時常會需要透過USB介面連接電腦主機與發展裝置。要達到這需求，程式發展人員要了解USB規範、編寫USB裝置程式、編寫主機端的驅動程式及應用程式。

在本論文中，我們結合軟硬體整合開發，建立一個USB裝置的連線。可以分為電腦主機及裝置兩部份來看，主機端需要作業系統上的應用程式及驅動程式，裝置端則需要裝置應用程式及USB Bus硬體驅動程式。

在主機端探討Windows AP啟用WDM驅動程式的方式，了解AP如何開啟裝置、傳送資料。另外還有WDM驅動程式的運作方式，了解WDM Driver在Windows作業系統如何掛載、使用系統資源、進行傳輸。

在裝置端則研究如何使用Embedded Linux內建的USB硬體驅動程式安裝GadgetFS，再用使用者模式的裝置程式以檔案格式形式存取GadgetFS接收、傳送USB匯流排傳送的資料。

本研究編寫了工具軟體以產生WDM驅動程式以及Linux裝置程式，在實際的開發板上驗證，我們已經確認可以使用工具軟體產生的Windows驅動程式及Linux裝置程式建立起USB連線，並且正確無誤的傳送資料。也可以在電腦主機的應用程式及Linux裝置程式加入新的功能，從電腦端傳送控制碼到開發板控制I/O，例如開發板的GPIO、ADC、DAC、LCD模組等等，都可以透過主機經由USB匯流排來控制。

Nowadays, USB devices are widely spread in use at our daily life. According to the demands of research purposes, sometimes embedded system developers need an USB interface connection between the host PC and developing environments. To fulfill this target requirement, developers need to understand USB SPEC., to build up the abilities to program USB Device function and host device driver/application as well.

In this research, we combine the developments of Windows SW and embedded Linux to build up an USB connection. In a host PC, it needs the Windows application and WDM Driver. In device side, it needs the Linux user mode application to implement device behavior and USB HW driver.

In the host, we study the method of how to activate the WDM Driver by a Windows application. Also study how does a Windows application open devices and transmit/receive data. The principle of WDM Driver is also a topic. We research how does the WDM Driver load in Windows OS, and how does it use system resource to communicate with devices.

In the device side, we study how to use the USB Driver of Linux Kernel built-in to install GadgetFS. Then, we mount the GadgetFS by a way of file system from the user mode application to transmit/receive data of USB bus.

The research also edits some utilities to generate the WDM Driver and Linux Device application. By approving on a physical developing board, it is successful to create the USB connection between host and device by the WDM Driver and Linux application which created by utilities. They transmit and receive data from each other accurately. Of course, we could add some more specific functions in the host and Linux application for some other research purposes. Such as GPIO, ADC, DAC, LCD module of the develop board, could control from host via the USB bus.
