The write() call in usb.c's ep_config() will go to ep_config() in inode.c. That routine does: fd->f_op = &ep_io_operations; And above you can see that in ep_io_operations, .unlocked_ioctl = ep_ioctl, When the ioctl() call occurs, it goes to do_vfs_ioctl() in fs/ioctl.c. >From there it goes to file_ioctl() and vfs_ioctl() in the same source file. Finally, vfs_ioctl() calls error = filp->f_op->unlocked_ioctl(filp, cmd, arg); So unless you messed up usb.c too badly, the ioctl() will invoke ep_ioctl().
