In Datasheet 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
