RemoteWakeupEnable:
This bit is used by HCD to enable or disable the remote
wakeup feature upon the detection of upstream resume
signaling. When this bit is set and the ResumeDetected bit
in HcInterruptStatus is set, a remote wakeup is signaled to
the host system. Setting this bit has no impact on the
generation of hardware interrupt.
Reserved. Unknown During Read.
HostControllerReset:
This bit is set by HCD to initiate a software reset of HC.
Regardless of the functional state of HC, it moves to the
USBSUSPEND state in which most of the operational
registers are reset except those stated otherwise; e.g., the
InterruptRouting field of HcControl, and no Host bus
accesses are allowed. This bit is cleared by HC upon the
completion of the reset operation. The reset operation
must be completed within 10 ms. This bit, when set,
should not cause a reset to the Root Hub and no
subsequent reset signaling should be asserted to its
downstream ports.
