Re: How would I get the raw data from a USB device ? (Transmitter USB adapter driver)

Nevermind... this works:

/*

============================================================================
 Name        : TransmitterAdapter.c
 Author      :
 Version     :
 Copyright   : 
 Description : 

============================================================================
 */

#include <stdio.h>
#include <stdlib.h>

int main(void) {
	printf("Transmitter Adapter Tester version 0.1\n");

	// open the joystick file
	FILE *joystick;

	joystick = fopen("/dev/input/js0", "rb");

	if (joystick == NULL)
		{
		printf("Joystick device file could not be opened.\n");
		printf("Exiting.\n");
		return(-1);
		}// if

	// now read a bunch of data and display it
	int i;
	int val;

	for (i=0;i<100;i++)
		{
		val = fgetc(joystick);
		printf("%2X\n", val);
		}

	exit(0);


	while (1)
		{
		for (i=0; i<8;i++)
			{
			val = fgetc(joystick);
			printf("%2X ", val);

			val = fgetc(joystick);
			printf("%2X ", val);

			val = fgetc(joystick);
			printf("%2X ", val);

			val = fgetc(joystick);
			printf("%2X ", val);

			val = fgetc(joystick);
			printf("%2X ", val);

			val = fgetc(joystick);
			printf("%2X ", val);

			val = fgetc(joystick);
			printf("%2X ", val);

			val = fgetc(joystick);
			printf("%2X \r", val);

			}//for
		}// while(1)

	return EXIT_SUCCESS;
}// End of main()
