I have here "Literature Number: SPRUH73H October 2011 ­ Revised April
2013" which calls itself "AM335x ARM® CortexTM-A8 Microprocessors
(MPUs) Technical Reference Manual".
This document ends with 16.5 that means there is no chapter 16.6 or
16.7. The next one is 17.
16.5.2 and 16.5.3 describes the available registers of
USB[01]_CTRL REGISTERS which is where the EOI register is accessed. I
see here

20h USB0IRQMSTAT
28h USB0IRQSTATRAW0

so no 0x24 at least in my document.

Sebastian
