These fields read logic 0, if the Port Power (PP) (bit 12 in register PORTSC 1,2,3,4) is logic 0.

Port Enabled/Disabled
: A logic 1 means enable. A logic 0 means
disable. Default = 0. Ports can only be enabled by the Host Controller
as a part of the reset and enable sequence. Software cannot enable a
port by writing a logic 1 to this field. The Host Controller will only set
this bit when the reset sequence determines that the attached device
is a high-speed device. Ports can be disabled by either a fault
condition or by host software. Note that the bit status does not change
until the port state has actually changed. There may be a delay in
disabling or enabling a port due to other Host Controller and bus
events. When the port is disabled, downstream propagation of data is
blocked on this port, except for reset.
[1]
Connect Status Change
: A logic 1 means Change in ECCS (Current
Connect Status). A logic 0 means no change. Default = 0. This bit
indicates a change has occurred in the port’s ECCS (Current Connect
Status). The Host Controller sets this bit for all changes to the port
device connect status, even if system software has not cleared an
existing connect status change. For example, the insertion status
changes twice before system software has cleared the changed
condition, hub hardware will be “setting” an already-set bit (that is, the
bit will remain set). Software clears this bit setting it.
[1]
Current Connect Status
: logic 1 indicates a device is present on
port. logic 0 indicates no device is present. Default = 0. This value
reflects the current state of the port and may not correspond directly to
the event that caused the ECSC (Connect Status Change) bit to be
set.
