Hi Grr,

Could you please test your driver with the following application:

/****************************************************************************
 * hello_main
 ****************************************************************************/

int main(int argc, FAR char *argv[])
{
  char name[32];
  int age;

  printf("Inform your name: ");
  scanf("%s", name);
  printf("Your name is: %s\n", name);

  printf("Inform your age: ");
  scanf("%d", &age);
  printf("Your age is: %d\n", age);

  return 0;
}

Currently the outout is printed this way:

Inform your name: Your name is: Alan
Inform your age: Your age is: 30

It didn't echoed the name and age while the user was typing and didn't
print the line break.

BR,

Alan
