openwrt使用3G上網卡

標籤：

尊敬的大大、感謝你抽空指導我
我的裝置是db120 mu350 和廣東無限卡
版本是OpenWrt Backfire 10.03.336 DIY full

一、        沒有安裝到kmod-usb-acm  為什嗎？



二、        我在終端入啟路由，插上MU350，WinSCP串連到路由，開啟終端輸入命令查看是否MU350已被識別。顯示如下  （與你所寫的不一樣，請問我的mu350識別了沒有）
/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、這一步省略了上面是講的3G上網卡的識別。如你的3G上網卡不能關閉儲存模式，那就要用到usb-modeswitch了，這個軟體前面我們已經裝了。
我們直接建立/etc/usb-modeswitch.conf,內容如下：
[Copy to clipboard] [ - ]
CODE:
# ZTE MU350
#
# Contributor: Dale Lane
DefaultVendor= 0x19d2;
DefaultProduct= 0x0003
# choose one of these:
DetachStorageOnly=0
MessageContent=5553424312345678000000000000061b000000020000000000000000000000

再執行usb_modeswitch -W，就能把MU350切換到modem模式了。

使用usb-modeswitch後，裝置不一定是/dev/usb/tts/0或者/dev/ttyUSB0，也有可能是/dev/usb/tts/1或者/dev/ttyUSB1

3G網卡的識別最重要的是/etc/usb-modeswitch.conf的建立，相關網卡的資訊需要大家一起研究和收集了。
另外如果華為的卡用usb-modeswitch不能被識別，可以試試安裝這個包：huaweiaktbbo
[Copy to clipboard] [ - ]
CODE:
opkg install huaweiaktbbo

然後直接運行命令：huaweiaktbbo
[Copy to clipboard] [ - ]
CODE:
huaweiaktbbo

3G 無線上網卡撥號 -- 以華為 EC189 為例

USB 3G 網卡預設模式為快閃記憶體裝置，使用 usb-modeswitch 切換 3G 網卡為 usbserial 模式，最終使用 pppd 撥接。

核心配置

只需選上 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
