本人最近做一个usb modem的Linux应用，设备本身能被windows识别成磁盘，由于自身带驱动、应用程序（中国移动的，M$ windoz上 L!!!），也能发送接收GPRS信息，而应用却在Linux上没有任何信息和资料。。。

 

没办法，既然能在M$ windoz上使用，那么也只有试试看了●０●

 

A.      测试

插上设备后：

还好Linux能识别此设备，当然被识别成磁盘了，心想，浮云也不过如此。

 

B.      信息

既然设备在M$ windoz上能正常使用，那么可从M$ windoz上找到些许信息，以帮助Linux开发。

通过M$ windoz找到 Philips Dev. 0 LUN USB

 

通过Google 关键字Philips Dev. 0 LUN USB Device linux driver找到下面文章：

http://www.epokh.org/blog/?p=357

 

C.       配置

找到usb_modemswitch,安装后，拷贝配置文件usb_modeswitch.conf，并修改设置如下：

 

DisableSwitching=0
# Enable logging (results in a extensive report file in /var/log, named
# "usb_modeswitch_<interface-name>" (and probably others)
EnableLogging=0
#0471:1202 Philips
DefaultVendor     = 0x0471
DefaultProduct    = 0x1202

TargetVendor      = 0x0471

CheckSuccess=20
InquireDevice=1

使用

 

usb_modeswitch -I -n -c /win/modem/usb-modeswitch/usb-modeswitch-1.1.6/release/etc/usb_modeswitch.conf

不管怎么改，楞是不成功！

到官方论坛上淘了好久：

几乎都差发帖了（最终还是忍不住，发帖了帖子链接在

后来从Josh 哪里得知

Seems like you don't have to switch anything, the serial ports are there. You just have to bind a driver to them.
In comes the magic of the Linux kernel; issue the following commands (as root or with sudo):

注意：当插拔后，发现端口变化了：

 

cdc_acm 2-1:1.0: ttyACM0: USB ACM device

usbcore: registered new interface driver cdc_acm

新的接口：ttyACM0

 

E.       使用：

 

好，开启minicom,设置为ttyUSB0,波特率（通过manual，或者使用串口调试助手（M$ windoz上的( -___- )b）找到当前模块的波特率），测试基本AT 命令。。。

 

AT+IPR=?  查询支持的DTE-DCE 波特率

AT+IPR?   读取当前的DTE-DCE 波特率

AT+IPR=   设置DTE-DCE 波特率

 

默认default : 57600

AT+IPR=57600

改为AT+IPR=115200

查看

好，现在终于能访问了！！！
