HPCON2..0: Hub Port Control Command
These bits are written by firmware to control the port states upon receipt of a Host request.
Disable Port
= ClearPortFeature(PORT_ENABLE)
Action:
USB hardware places addressed port in disabled state. Port 1 is placed in disabled
state by firmware.
Enable Port
= SetPort Feature(PORT_ENABLE)
Action:
USB hardware places addressed port in enabled state. Firmware is responsible for
placing Port 1 in enabled state.
Reset and Enable Port
= SetPort Feature(PORT_RESET)
Action:
USB hardware drives reset signaling through addressed port. USB hardware and
firmware resets their embedded function registers to the default state.
Suspend Port
= SetPortFeature(PORT_SUSPEND)
Action:
USB hardware places port in idle state and stops propagating traffic through the
addressed port. Firmware places Port 1 in suspend state by disabling its endpoints and plac-
ing the peripheral function in its low power state.
Resume Port
= ClearPortFeature(PORT_SUSPEND)
Action:
USB hardware sends resume signaling to addressed port and then enables port.
Firmware takes the embedded function out of the suspend state and enables Port 1's
endpoints.
