10.1.5 HcInterruptEnable register (R/W: 04H/84H)
Table 15:
Each enable bit in the HcInterruptEnable register corresponds to an associated
interrupt bit in the HcInterruptStatus register. The HcInterruptEnable register is used
to control which events generate a hardware interrupt. A hardware interrupt is
requested on the host bus when three conditions occur:

Description
reserved
RootHubStatusChange: This bit is set when the content of
HcRhStatus or the content of any of HcRhPortStatus[1:2] has
changed.
FrameNumberOverflow: This bit is set when the MSB of
HcFmNumber (bit 15) changes value.
UnrecoverableError: This bit is set when the HC detects a
system error not related to USB. The HC does not proceed with
any processing nor signaling before the system error has been
corrected. The HCD clears this bit after the HC has been reset.
OHCI: Always set to logic 0.
ResumeDetected: This bit is set when the HC detects that a
device on the USB is asserting resume signaling from a state of no
resume signaling. This bit is not set when HCD enters the
USBResume state.
StartofFrame: At the start of each frame, this bit is set by the HC
and an SOF is generated.
reserved
SchedulingOverrun: This bit is set when the USB schedules for
current frame overruns. A scheduling overrun will also cause the
SchedulingOverrunCount of HcCommandStatus to be
incremented.
