Atmel At90USB (AVR with USB) Enumeration

In Data*** for AT90USB1287 (7593C–AVR–05/06 Preliminary)
we can read on page 274 (22. USB Device Operating modes):
"CONTROL endpoints should not be managed by interrupts, but only by polling
the status bits."
Can someone tell me why I should not use interrupts for handling enumeration
and control standard requests? How should I handle polling -- I think I
need a timer interrupt for periodically polling, in this case.
Best regards
Stefan Salewski
