Q1. How to compile
-----------------------
The driver interface was developed on wpa_supplicant v.0.4.7.
You can install the WPA Supplicant Free Edition development from website.

	http://hostap.epitest.fi/wpa_supplicant/
	
After download the package then go to wpa_supplicant directory
Follow the steps..

1.) Copy file "driver_ralink.c" and "driver_ralink.h" we provide to wpa_supplicant directory. 
2.) Set driver_ralink configuration as y in the "defconfig" or update to the "defconfig" we provide::

# Driver interface for Ralink rt73 driver
CONFIG_DRIVER_RALINK=y
    
3.) Add wpa_driver_ralink_ops() into wpa_supplicant_drivers() in file "drivers.c" 
    or update to the file "drivers.c" we provide:: 
    
#ifdef CONFIG_DRIVER_RALINK
extern struct wpa_driver_ops wpa_driver_ralink_ops; /* driver_ralink.c */
#endif /* CONFIG_DRIVER_RALINK */
    :
    :
struct wpa_driver_ops *wpa_supplicant_drivers[] =
{ 
#ifdef CONFIG_DRIVER_RALINK
	&wpa_driver_ralink_ops,
#endif /* CONFIG_DRIVER_RALINK */  
}
    
4.) Edit the "Makefile" or update to the "Makefile" we provide::

ifdef CONFIG_DRIVER_RALINK
CFLAGS += -DCONFIG_DRIVER_RALINK
OBJS_d += driver_ralink.o
endif

5.) type $cp defconfig .config
6.) Compile the source code using 'make' command.
    

Q2. How to start wpa_supplicant
--------------------------------
1.) First start rt73 driver.

2.) Edit/Create a configuration file of wpa_supplicant.
   -a)  Set your work directory of wpa_supplicant for sockets
        ctrl_interface = YOUR_WORK_PATH
        
   -b)  Set YOUR_OPENSC_PATH if need be. (e.g. generate certificates)
        opensc_engine_path =/YOUR_OPENSC_PATH/engine_opensc.so
        pkcs11_engine_path =/YOUR_OPENSC_PATH/engine_pkcs11.so
        pkcs11_module_path =/YOUR_OPENSC_PATH/opensc-pkcs11.so

   -c)  Set network configuration. (e.g. WPA/EAP-TTLS)
   
    *** refer to wpa_supplicant.conf in details or related documents ***
    
3.) Manually start wpa_supplicant, 
    type $./wpa_supplicant -c your_config_file -i rausb0 -D ralink

    turn on debug mode,
    type $./wpa_supplicant -c your_config_file -i rausb0 -D ralink -d
