一、 開發(fā)環(huán)境
板子：海思3716C
dongle：華為EC122
虛擬機(jī)：ubuntu10.10
在這里參照了一篇博文，由于所移植的上網(wǎng)卡是一個(gè)型號(hào)，省去了找資料的很多麻煩，蒼天啊，大地啊，感動(dòng)。呵呵
http://blog.csdn.net/liuming_3385/archive/2011/02/24/6206306.aspx
二、以前也移植過一個(gè)dongle，那次是稀里糊涂的搞了半個(gè)月，最后雖然能夠撥號(hào)上網(wǎng)了，但是不穩(wěn)定，在移植中對一些知識(shí)的了解也是一知半解。通過這次的移植，了解了3G上網(wǎng)卡的工作流程。需要的工具：ppp-2.3.5.tar.gz udev-100.tar.bz2
1、libusb-0.1.12.tar.gz 下載地址：http://www.libusb.org/
libusb 是一個(gè)用C語言開發(fā)的跨平臺(tái)的USB設(shè)備訪問接口庫。libusb 設(shè)計(jì)了一系列的外部API 為應(yīng)用程序所調(diào)用，通過這些API應(yīng)用程序可以操作硬件，從libusb的源代碼可以看出，這些API 調(diào)用了內(nèi)核的底層接口，和kernel driver中所用到的函數(shù)所實(shí)現(xiàn)的功能差不多，只是libusb更加接近USB 規(guī)范。使得libusb的使用也比開發(fā)內(nèi)核驅(qū)動(dòng)相對容易的。需要注意的是libusb有兩個(gè)版本，0.1 和 1.0版本，usb-modeswitch依賴libusb，但是1.0版本的編譯不過。源碼里有標(biāo)準(zhǔn)的automake 工具生成的configure文件，直接交叉編譯。
2、usb-modeswitch-1.1.7.tar.bz2 下載地址：http://www.draisberghof.de/usb_modeswitch/
主頁說明：
USB_ModeSwitch is (surprise!) a mode switching tool for controlling "flip flop" (multiple device) USB gear.
Several new USB devices (especially high-speed WAN stuff, based on cell phone chipsets containing that feature) have their MS Windows drivers onboard; when plugged in for the first time they act like a flash storage and start installing the driver from there. After installation (and on every consecutive plugging) the driver switches the mode internally, the storage device vanishes (in most cases), and a new device (like an USB modem) shows up. Modem maker "Option" calls that feature "ZeroCD (TM)" since it eliminates the need for shipping a separate driver carrier.
In the beginning, nothing of this was documented in any form and there was hardly any Linux support available.
On the good side, most of the known devices do work in both modes with the available Linux drivers like "usb-storage" or "option" (an optimized serial driver for high-speed modems).That leaves only the problem of the mode switching from storage to modem or whatever the thing is supposed to do.
Fortunately there are things like human reason, USB sniffing programs and "libusb". It is possible to eavesdrop the communication of the MS Windows driver, to isolate the command or action that does the switching and to reproduce the same thing under the rule of Linux or the BSD variants.
USB_ModeSwitch makes this process easy to handle by taking the important parameters from a configuration file and doing all the initialization and communication stuff, with heavy help from "libusb".
It is mainly used automatically - via udev events and rules - to do the switch without any user interaction. But it can also be run as a command line tool, usually when trying to make unknown devices work with it.
USB_ModeSwitch 是控制"flip flop"(多重設(shè)備)USB裝置的模式轉(zhuǎn)換工具, 現(xiàn)在一些新的USB 設(shè)備(特別是一些高速 WAN 設(shè)備，如3G數(shù)據(jù)卡)都有MS Windows的驅(qū)動(dòng)程序，當(dāng)?shù)谝淮尾迦霗C(jī)子的時(shí)候，它們處于閃存模式，并從中提取和安裝驅(qū)動(dòng)。在驅(qū)動(dòng)安裝完畢之后，驅(qū)動(dòng)馬上轉(zhuǎn)換模式，儲(chǔ)存設(shè)備消失(基本上都是這樣的)，然后一個(gè)新的設(shè)備(比如一個(gè)USB modem)出現(xiàn)。有些人把這個(gè)特性叫做"ZeroCD"。
1． Usb 閃存模式：提取和安裝驅(qū)動(dòng)
2． 轉(zhuǎn)換模式：儲(chǔ)存設(shè)備模式轉(zhuǎn)換為所需（如3G）設(shè)備模式
3． 所需設(shè)備模式：使用設(shè)備新的功能
編譯修改Makefile ，指定交叉編譯工具鏈和libusb的頭文件和庫的位置：
root@wang:/work/dongle/usb-modeswitch-1.1.7# cat Makefile -n
1 DESTDIR = /work/dongle/rootfs
2 PROG = usb_modeswitch
3 VERS = 1.1.7
4 CC = mipsel-linux-gcc
5 STRIP = mipsel-linux-strip
6 CFLAGS += -Wall
7 LIBS = -l usb
8 RM = /bin/rm -f
9 OBJS = usb_modeswitch.c
10 PREFIX = $(DESTDIR)/usr
11 ETCDIR = $(DESTDIR)/etc
12 UDEVDIR = $(DESTDIR)/lib/udev
13 SBINDIR = $(PREFIX)/sbin
14 MANDIR = $(PREFIX)/share/man/man1
15 CFLAGS += -I /work/dongle/rootfs/include
16 CFLAGS += -L /work/dongle/rootfs/lib
修改 usb_modeswitch.conf 文件，加入設(shè)備的信息：這一步很關(guān)鍵，資料不好找啊，除非生產(chǎn)廠提供支持。在usb-modeswitch-1.1.7目錄下有device_reference.txt文件，在這里可以查到一些設(shè)備的信息，但不完整。關(guān)于設(shè)備的Vendor Product可以通過另外一種方法，在后邊會(huì)看到。
root@wang:/work/dongle/usb-modeswitch-1.1.7# cat usb_modeswitch.conf
# Configuration for the usb_modeswitch package, a mode switching tool for
# USB devices providing multiple states or modes
#
# This file is evaluated by the wrapper script "usb_modeswitch_dispatcher"
# in /usr/sbin

# Everything else counts as "disable"

3、udev-100.tar.bz2 下載地址：http://www.kernel.org/pub/linux/utils/kernel/hotplug/
使用更高版本的udev沒編譯過。
udev是一個(gè)工作在用戶空間的設(shè)備管理工具。在USB_ModeSwitch 的介紹中我們已經(jīng)知道，USB_ModeSwitch 依賴于udev實(shí)現(xiàn)熱插熱拔。
修改Makefile：
93 prefix ?=$(PWD)/rootfs
94 etcdir = ${prefix}/etc
95 sbindir = ${prefix}/sbin
96 usrbindir = ${prefix}/usr/bin
97 usrsbindir = ${prefix}/usr/sbin
98 libudevdir = ${prefix}/lib/udev
99 mandir = ${prefix}/usr/share/man
100 configdir = ${etcdir}/udev
101 udevdir = /dev
102 DESTDIR =
103
104 INSTALL = /usr/bin/install -c
105 INSTALL_PROGRAM = ${INSTALL}
106 INSTALL_DATA = ${INSTALL} -m 644
107 INSTALL_SCRIPT = ${INSTALL_PROGRAM}
108 PWD = $(shell pwd)
109
110 CROSS_COMPILE ?=mipsel-linux-
111 CC = $(CROSS_COMPILE)gcc
112 LD = $(CROSS_COMPILE)gcc
113 AR = $(CROSS_COMPILE)ar
4、完事具備，還欠東風(fēng)。設(shè)備節(jié)點(diǎn)準(zhǔn)備完以后，還需要撥號(hào)工具上網(wǎng)。這就需要PPPD工具上場了。
修改configure文件：
root@wang:/work/dongle/ppp-2.4.5# cat configure -n
1 #!/bin/sh
2 # $Id: configure,v 1.38 2008/06/15 07:08:49 paulus Exp $
3
4 # Where to install stuff by default
5 export CC=mipsel-linux-gcc
6 DESTDIR=$PWD/rootfs/usr/local
7 SYSCONF=$PWD/rootfs/etc
運(yùn)行 ./configure 生成Makefile。
修改Makefile 將install 命令中的 -s 選項(xiàng)去掉。
生成的工具和庫中我們需要的是pppd chat rp-pppoe.so
5、將生成的可執(zhí)行文件和庫復(fù)制到根文件系統(tǒng)。將各種配置文件復(fù)制到根文件系統(tǒng)。usb_modeswitch.conf 將安裝udev時(shí)生成的/etc/udev目錄復(fù)制到根文件系統(tǒng)的/etc 下；將、ppp-2.4.5/etc.ppp 目錄下的內(nèi)容復(fù)制到/etc/ppp目錄下。根據(jù)上邊介紹的攻略生成PPPD 的配置文件并放到根文件系統(tǒng)的相應(yīng)目錄。
6、掛載根文件系統(tǒng)
