openwrt使用3G上网卡

尊敬的大大、感谢你抽空指导我

我的设备是db120 mu350 和广东无限卡

版本是OpenWrt Backfire 10.03.336 DIY full

一、        没有安装到kmod-usb-acm  为什么？

二、        我在终端入启路由，插上MU350，WinSCP连接到路由，打开终端输入命令查看是否MU350已被识别。显示如下  （与你所写的不一样，请问我的mu350识别了没有）

/etc/modules.d$ dmesg | grep usb

usbcore: registered new interface driver usbfs

usbcore: registered new interface driver hub

usbcore: registered new device driver usb

usbcore: registered new interface driver rtl8187

usbcore: registered new interface driver p54usb

usb usb1: configuration #1 chosen from 1 choice

usb usb2: configuration #1 chosen from 1 choice

usb 2-1: new full speed USB device using bcm63xx_ohci and address 2

usbcore: registered new interface driver usblp

usbcore: registered new interface driver usbserial

usb 2-1: configuration #1 chosen from 1 choice

usbserial_generic 2-1:1.0: generic converter detected

usb 2-1: generic converter now attached to ttyUSB0

usbcore: registered new interface driver usbserial_generic

usbserial: USB Serial Driver core

usbcore: registered new interface driver usb-storage

usbcore: registered new interface driver zd1211rw

三、这一步省略了上面是讲的3G上网卡的识别。如你的3G上网卡不能关闭存储模式，那就要用到usb-modeswitch了，这个软件前面我们已经装了。

我们直接新建/etc/usb-modeswitch.conf,内容如下：

[Copy to clipboard] [ - ]

CODE:

# ZTE MU350

#

# Contributor: Dale Lane

DefaultVendor= 0x19d2;

DefaultProduct= 0x0003

# choose one of these:

DetachStorageOnly=0

MessageContent=5553424312345678000000000000061b000000020000000000000000000000

再执行usb_modeswitch -W，就能把MU350切换到modem模式了。

使用usb-modeswitch后，设备不一定是/dev/usb/tts/0或者/dev/ttyUSB0，也有可能是/dev/usb/tts/1或者/dev/ttyUSB1

3G网卡的识别最重要的是/etc/usb-modeswitch.conf的创建，相关网卡的信息需要大家一起研究和收集了。

另外如果华为的卡用usb-modeswitch不能被识别，可以试试安装这个包：huaweiaktbbo

CODE:

opkg install huaweiaktbbo

然后直接运行命令：huaweiaktbbo

3G 无线上网卡拨号 -- 以华为 EC189 为例

USB 3G 网卡默认模式为闪存设备，使用 usb-modeswitch 切换 3G 网卡为 usbserial 模式，最终使用 pppd 拨号上网。

内核配置

只需选上 ppp 和 usbserial

DeviceDrivers --->

[*] Network device support-->

<*> PPP (point-to-point protocol) support

[*] PPP multilink support (EXPERIMENTAL)

[*] PPP filtering

<*> PPP support for async serial ports

<*> PPP support for sync tty ports

<*> PPP Deflate compression

<*> PPP BSD-Compress compression

<*> PPP MPPE compression (encryption) (EXPERIMENTAL)

[*]USB support --->

<*> USB Serial Converter support --->

[*] USB Generic Serial Driver

<*> USB driver for GSM and CDMA modems
