Over-current Active (OCACT_P0_0): 1=This port currently has an over-
current condition. 0=This port does not have an over-current condition. This
bit will automatically transition from a one to a zero when the over current
condition is removed. The functionality of this bit is not dependent upon the
port owner. The Intel EHC automatically disables the port when the over-
current active bit is '1'.

Port Enable/Disable Change (PEDC_P0_0): 1=Port enabled/disabled
status has changed. 0=No change. For the root hub, this bit gets set to a one
only when a port is disabled due to the appropriate conditions existing at the
EOF2 point (See Chapter 11 of the USB Specification for the definition of a
port error). This bit is not set due to the Disabled-to-Enabled transition, nor
due to a disconnect. Software clears this bit by writing a 1 to it.

Connect Status Change (CSC_P0_0): 1=Change in Current Connect
Status. 0=No change. Indicates a change has occurred in the port's 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 (i.e., the bit will remain set). Software sets this
bit to 0 by writing a 1 to it.

Current Connect Status (CCS_P0_0): 1=Device is present on port. 0=No
device is present. This value reflects the current state of the port, and may
not correspond directly to the event that caused the Connect Status Change
bit (Bit 1) to be set.
