1.在 linux_src/include/linux/usb.h 中添加如下宏

若部分内核已经添加，则无需添加此部分。详文如下：

#define USB_VENDOR_AND_INTERFACE_INFO(vend, cl, sc, pr) \

.match_flags = USB_DEVICE_ID_MATCH_INT_INFO \

| USB_DEVICE_ID_MATCH_VENDOR, \

.idVendor = (vend), \

.bInterfaceClass = (cl), \

.bInterfaceSubClass = (sc), \

.bInterfaceProtocol = (pr)

2.在 linux_src/drivers/usb/serial/option.c 文件中的 static const struct

usb_device_id option_ids[]的 id 列表中增加如下语句,用于匹配设备数据。

{VID,InterfaceClass, InterfaceSubClass, InterfaceProtocol}。

{ USB_VENDOR_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0xff,

0xff) },

{ USB_VENDOR_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x01,

0x01) },

{ USB_VENDOR_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x01,

0x02) },

{ USB_VENDOR_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x01,

0x03) },

{ USB_VENDOR_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x01,

0x04) },

{ USB_VENDOR_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x01,

0x05) },

............

3.在option.c中加入定义

增加对 bcdUSB 值的定义：#define HW_bcdUSB 0x0110；

增加对华为 vid 值的定义：#define HUAWEI_VENDOR_ID 0x12d1。

#define HUAWEI_PRODUCT_MU709S            0x1c25 //add by cxy

#define HUAWEI_PRODUCT_ME909             0x15c1 //add by cxy

{ USB_DEVICE(HUAWEI_VENDOR_ID, HUAWEI_PRODUCT_MU709S) },//add by cxy

{ USB_DEVICE(HUAWEI_VENDOR_ID, HUAWEI_PRODUCT_ME909) },//add by cxy

4.内核配置

1)USB driver for GSM and CDMA midems

2)ppp拨号 ppp BSD-compres comprossion

3)CDC相关

4.ppp拨号脚本

编译ppp2.2.4  pppd chat 放入文件系统/usr/sbin中

2种方式

1.huawei-ppp-on huawie-ppp-off...

2.evdo   evdo-chat-connect
