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

CODE:

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
