openwork + 3g usb modem(中兴 MF667s)¶
安装如下应用包¶
First install required packages:
* comgt manpage for comgt
* Appropriate host controller interface for your USB hardware (precompiled images will most likely already contain the correct one)
* kmod-usb2 (aka EHCI)
* kmod-usb-ohci
* kmod-usb-uhci (for example VIA chips)
* Support for serial communication; needed to send control commands to the dongle and receive its responses.
* kmod-usb-serial, and
* kmod-usb-serial-option, and
* kmod-usb-serial-wwan, or
* kmod-usb-acm i.s.o. the last two, depending on dongle/phone hardware.
* kmod-usb-serial-option is not available for 2.4 kernel, install kmod-usb-serial and put a line equivalent to "usbserial vendor=0x12d1 product=0x1003 maxSize=2048" in /etc/modules.d/60-usb-serial)
* modeswitching tools, if your modem initially presents itself as a storage device - one of the following, depending on your modem:
* usb-modeswitch and usb-modeswitch-data (recommended) A mode switching tool for controlling "flip flop" (multiple device) USB gear.
Note: as of r36812, usb-modeswitch package had been under major overhaul from ordinary draisberghof usb_modeswitch found in many linux distributions. usb-modeswitch-data is included in the package, with the new json format.
* sdparm - utility to send SCSI commands (needed on Ovation MC935D)
* luci-proto-3g for proper support in luci in RC6 and later
opkg update
opkg install comgt kmod-usb-serial kmod-usb-serial-option kmod-usb-serial-wwan usb-modeswitch usb-modeswitch-data
使用option GSM 驱动usb切换后的串口。¶
注意，这里的vid和pid为切换到usb modem模式后的vid和pid。
insmod option #skip this if option driver is loaded already
echo '<vid> <pid> ff' > /sys/bus/usb-serial/drivers/option1/new_id
使用usb-modeswitch切换usb模式¶
- 创建 /etc/usb_modeswitch.conf 文件，并添加如下类容，这些内容由usb modem设备制造商提供
DefaultVendor=0x19d2
DefaultProduct=0x1588
TargetVendor=0x19d2
TargetProduct=0x1589 MessageContent="55534243123456782000000080000c85010101180101010101000000000000"
- 执行 usb_modeswitch -W -c /etc/usb_modeswitch.conf -I 命令 查看dmesg是否有如下输出，并查看/dev下是否有ttyUSB0~ttyUSB3

同时可以查看 /proc/bus/usb/devices 文件，注意红色的部分。

配置网络接口¶
编辑 /etc/config/network 文件
config interface wan
# option ifname ppp0 # on some carriers enable this line
option pincode 1234
option device /dev/ttyUSB0
option ap n 3gnet
option service umts
option proto 3g
配置拨号脚本¶
修改 /etc/chatscripts/3g.chat 文件，
- 运行，这个命令可以注册网络。 gcom -d /dev/ttyUSB0
- 运行‘ifup wan’拨号。要等上个几秒钟
ABORT BUSY
ABORT 'NO CARRIER'
ABORT ERROR
REPORT CONNECT
TIMEOUT 12
"" "AT&F"
OK "ATE1"
OK 'AT+CGDCONT=1,"IP","$USE_APN"'
ABORT 'NO CARRIER'
TIMEOUT 15
OK "ATD*99#"
CONNECT ' '
这里dmesg里没有信息。可以查看usb modem卡上的等（蓝色常亮）。
使用ifconfig查看¶
