To code computer side usbgecko application you need :


I have started a linux application, all seems ok, except the ftdi_read_data that always return 0 :/ For those who interrested this page can be a base to make a usable application.

#include <stdio.h>
#include <sys/types.h>
#include <ftdi.h> 

//--------------------------  Globals ----------------------------------
int32_t status;
int ret;
int32_t TxSent;
int32_t RxSent;

struct ftdi_context ftdic;

int cmd_readmem = 0x04;
//--------------------------  Function Prototypes ----------------------------------
void gecko_opendevice(); 




int main(int argc, char **argv)
{
	void* plop; 
	unsigned char responseback = 0;

	ftdi_init(&ftdic);


	printf("-----------------------------------\n");
	printf("- NoNameNo's UsbGecko Linux Tools -\n");
	printf("-----------------------------------\n\n");

	gecko_opendevice();
	printf("Connecting to Wii.\n");
	printf("%x\n",gecko_writebyte(&cmd_readmem,1));
	printf("%x\n",gecko_readbyte(&responseback, 1));
	ftdi_usb_close(&ftdic);
	ftdi_deinit(&ftdic);

	return EXIT_SUCCESS;
}
//----------------------------------------------------------------------------------------------------
//----------------------------------------------------------------------------------------------------
//----------------------------------------------------------------------------------------------------
int gecko_readbyte(unsigned char* lpBuffer, int dwBytesToRead)
{
	status = ftdi_read_data(&ftdic, lpBuffer, dwBytesToRead);
	
	if (status > 0){
		if(status != dwBytesToRead){
			return 2;
		}
	}
	else{
		printf("[Error] UsbGecko Reading Device\n");
		//ftdi_usb_close(&ftdic);
		//ftdi_deinit(&ftdic);
		return status;
	}
		
	return 1;
}

//----------------------------------------------------------------------------------------------------
//----------------------------------------------------------------------------------------------------
//----------------------------------------------------------------------------------------------------
int gecko_writebyte(unsigned char* lpBuffer, int dwBytesToWrite)
{
	status = ftdi_write_data(&ftdic, lpBuffer, dwBytesToWrite);
	
	if (status > 0){
		if(status != dwBytesToWrite){
			return 2;
		}
	}
	else{
		printf("[Error] UsbGecko Writing Device\n");
		ftdi_usb_close(&ftdic);
		ftdi_deinit(&ftdic);

	return 1;

	}
	else{

	}


//---------------------------Reset device --------------------------------------
	if((ret = ftdi_usb_reset(&ftdic)) < 0) {

	ftdic.usb_read_timeout=2000;
