The probe function of device driver assigns the minor number. Since you
have only 1 ub, it will use minor numbers 0 to 7. Possibly registering up
to 8 partitions:
disk->first_minor = sc->id * UB_MINORS_PER_MAJOR;
by calling add_disk().
On the other side, device nodes creation could have been done
automatically through devfs.
