The USB Interrupt Enable register (Register 14-8)
contains the enable bits for the USB status interrupt
sources. Setting any of these bits will enable the
respective interrupt source in the UIR register.

The values in this register only affect the propagation
of an interrupt condition to the microcontroller’s
interrupt logic. The flag bits are still set by their
interrupt conditions, allowing them to be polled and
serviced without actually generating an interrupt.
