Sorry but I did not understand you.
Once that I disconnect with this program:
nt main(){
struct usbdevfs_ioctl ctrl;
int fd;
fd = open("/proc/bus/usb/002/003", O_RDWR);
if(fd != -1) {
ctrl.ifno = 0;
ctrl.ioctl_code = USBDEVFS_DISCONNECT;
ioctl(fd, USBDEVFS_IOCTL, &ctrl);
perror("ioctl");
close(fd);
}
return 0;
}
I received that:
ioctl: Success
syslog said:
udev[9242]: removing device node '/dev/usb/hiddev0'
when I claim with this program:
int main(){
int fd;
int interface=0,*inter;
inter=&interface;
fd = open("/proc/bus/usb/002/003", O_RDWR);
if(fd != -1) {
ioctl(fd, USBDEVFS_CLAIMINTERFACE, &interface);
perror("ioctl");
close(fd);
}
return 0;
}
I received that:
ioctl: Success
And syslog did not said anything
when I try to send data with:
int main(){
struct usbdevfs_bulktransfer bulk;
int fd;
int ret,*data,dato=0xFF;
data=&dato;
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_BULK, &bulk);
perror("ioctl");
close(fd);
}
return 0;
}
I received:
ioctl: Invalid argument
And syslog said that:
kernel: usb 2-1: usbfs: process 9272 (enviar) did not claim interface
0 before use
kernel: usb 2-1: usbfs: USBDEVFS_BULK failed ep 0x1 len 4 ret -22
Thank you
And sorry but my english is not good.
