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 generated.
reserved
SchedulingOverrun: This bit is set when USB schedules for current
frame overruns. A scheduling overrun will also cause the
SchedulingOverrunCount of HcCommandStatus to be incremented.
