同样要修改Quectel_LTE5G_Linux_USB_Driver_V1.0-5/Quectel_LinuxAndroid_QMI_WWAN_Driver_V1.1/qmi_wwan_q.c源文件，在

static const struct usb_device_id products[] = {

#if 1 //Added by Quectel

最后面添加{ QMI_FIXED_RAWIP_INTF(0x2C7C, 0x6005, 4) },

这样insmod qmi_wwan_q.ko后才会出现/dev/cdc-wdm0这个设备文件。

没有/dev/cdc-wdm0文件的话，quectel-CM程序无法运行成功。
