Drive section:

1.kernle/drivers/usb/serial/option.c structure array static struct usb_device_id option_ids[] added vid and PID added to the product

{Usb_device (0x1c9e, 0x9e00)}//u5300v/c7500 EVDO

{Usb_device (0x1c9e, 0x9603)}//6300v/u7500 WCDMA

{Usb_device (0x1c9e, 0X9B05)}//U8300 LTE

2. If dial-up Internet is configured after Ppp,make Menuconfig

Device Drivers--->

-*-network Device Support--->

{*}PPP (Point-to-Point Protocol) support

......

[*] PPP support for async serial ports

[*] PPP support for sync TTY ports

......

Generally select the above, if more PPP services are needed, PPP correlation is selected.

......

3. Configure the USB MODEM

Device Drivers--->

[*] USB Support--->

[*] USB Serial conerter Support--->

[*] USB Generic Serial Driver

......

[*] USB driver for GSM and CDMA modems

......

Recompile the kernel. After the device loads properly, you will see a ttyusb (0,1,2,-,-) map after entering the command "ls/dev/ttyusb*".

4. Module Pid&vid and corresponding business port assignment

u6300v/u7500:vid_1c9e pid_9603 ttyUSB1 is at Port ttyUSB2 Modem port;

c5300v/c7500:vid_1c9e pid_9e00 ttyUSB3 is at Port ttyUSB0 Modem port;

u8300:vid_1c9e pid_9b05 ttyUSB2 is at Port ttyUSB1 Modem port;

System Application Section:

First, using the modem port, PPP dialing method

1, at the port is mainly used for network information query, voice services, SMS, etc.

2, modem port for data services, through at the port to check the network Registration network normal and then initiate dialing processing;

3, the dial script mainly has two configuration files, take WCDMA as an example:

A, in/ETC/PPP/PEERS/WCDMA:

/dev/ttyusb2

Perform a WCDMA file dialing.

Note: If it is a EVDO module, the parameters in a file are

User Card

Password card;

If it is an LTE module, the Cgdcont of the B file is set up in two ways, i.e.

Ok at+cgdcont=1, "IP", "CMNET"

Ok at+cgdcont=2, "IP", "CMNET"

Hardware manual for the corresponding module "XXX Module hardware interface manual _2.x. In the "USB Interface" section of the PDF.

"The Linux system under the dial-up Internet process" is also described in detail. Please refer to the appropriate documentation

Second, LTE module NDIS dialing Method

LTE module provides the network port NDIS dialing method, because the operation method is more complex, the Dragon has already provided the dialing code for this dialing method, facilitates the customer to transplant, and has done the detailed explanation to its operation, the concrete may refer to:

document A:"Linux QMI NDIS dialing API description. pdf"

Document B:"description of NDIS compilation and usage in embedded Linux systems. pdf"

Please contact the technical interface to obtain the relevant documentation.
