17.5.2
The USB Interrupt Enable register (Register 17-8)
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 inter-
rupt logic. The flag bits are still set by their interrupt
conditions, allowing them to be polled and serviced
without actually generating an interrupt.
