¡Vhttp://www.asus.com/index.aspx
2. Choose ¡§Download¡¨
3. Select Product
¡VEeePC??¡§EeePC Series¡¨your EeePCmodel
4. Download Source Code
¡V¡§Linux_Kernel_071127.rar ¡¨
5. Extract Source Code
¡VOutput ¡§linux-source-2.6.21.4-eeepc_5_all.deb ¡¨
¡Esudorarx Linux_Kernel_071127.rar (If you have RAR on EeePC)
¡Eor you can extract it with other tools


Update Driver Source Code Update Driver Source Code
1. Update cdc-acm.c
in /drivers/usb/class/
2. The only difference is
adding Vendor and Product
ID¡¦sfor MT3329 USB Solution

To Find static struct usb_device_id acm_ids[]
Add (please follow coding rule )
{ USB Device(0x0e8d,0x3329), /* Meditek GPS USB function */
.driver_info =No_UNICN_NORMAL, /* has no union descriptor */
}


Make Module for MT3329 USB Make Module for MT3329 USB
1. Change path to /drivers/usb/class
¡Vcd/drivers/usb/class
2. Build module for cdc-acm
¡Vsudomake
¡Vor you can use ¡§sudomake install¡¨to make all kernel source
¡EYou may need to following current configuration of EeePC
sudocp /boot/config-2.6.21.4-eeepc .config



Insert Module to System

How to Get GPS Data through USB Port How to Get GPS Data through USB Port
1. Plug in MT3329 USB device
¡VThe device can be found in /dev/, and naming ¡§ttyACM0¡¨
2. Catch GPS NMEA data
¡Vminicom
¡VIf you don¡¦t have tools like minicomin linux, you can directly catch the log and save in a file
¡Ecat /dev/ttyACM0 >~/Output.txt
¡EThe NMEA data will be saved in Output.txt
