You don't have to use the DISCONNECT ioctl. Instead you can just do:
rmmod usbhid.
If you do want to use the ioctl, you need to do it correctly:
struct usbdevfs_ioctl ctrl;
ctrl.ifno = 0; /* Interface number */
ctrl.ioctl_code = USBDEVFS_DISCONNECT;
ioctl(fd, USBDEBVFS_IOCTL, &ctrl);

It doesn't matter. It's okay to use USBDEVFS_BULK for an interrupt
transfer.
