I made this program
int main(){
struct usbdevfs_bulktransfer bulk;
struct usbdevfs_ioctl ctrl;
int fd;
int ret,*data,dato=0xFF,interface=0x00,*inter;
//data=&dato;
inter=&interface;
fd = open("/proc/bus/usb/002/003", O_RDWR);
if(fd != -1) {
//bulk.ep = USB_DIR_IN | 1;
bulk.ep = 1;
bulk.len = 4;
bulk.data = data;
bulk.timeout = 1000;
//bulk.data = malloc(1024);
ioctl(fd, USBDEVFS_CLAIMINTERFACE, &interface);
perror("ioctl");
ret=ioctl(fd, USBDEVFS_BULK, &bulk);
perror("ioctl");
if (ret < 0)
printf("Error in bulk transfer\n");
close(fd);
}
return 0;
}
But I did not receive anything, and syslog did not say anything.
It can that has worked?
Thank you again
