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
