1 = Reset complete
This bit is set by the USB hardware after it completes RESET signaling which is initiated when
the Reset and Enable Port command is detected at the Port Control Register, HPCON. The firm-
ware sends this command when it decodes a SetPortFeature(PORT_RESET) request from the
host.
At EOF2 after the hardware completes the port reset, the hardware sets the Port Enable Status
bit and clears the Port Reset Status bit of the Hub Port Status Register, HPSTAT. Cleared by
firmware, ClearPortFeature(PORT_RESET).
Bit 3 – POCIC: Port Overcurrent Indicator Change
0 = No change has occurred on Overcurrent Indicator
1 = Overcurrent Indicator has changed
This bit is relevant to hubs with individual overcurrent reporting only. The firmware sets this bit
as a result of detecting overcurrent at the ports OVC# pin. The firmware clears bit through Clear-
PortFeature(PORT_OVER_CURRENT). For Port 1, this bit is always cleared.
Bit 2 – PSSC: Port Suspend Status Change
0 = No change
1 = Resume completed
Port 2, 3 set by hardware upon completion of firmware initiated resume process. Port 1 set by
firmware 20 ms after the next EOF2 after completion of resume process. RESUME signaling is
initiated through global resume, selective resume and remote wakeup. Cleared by firmware via
host request ClearPortFeature(PORT_SUSPEND).
Bit 1 – PESC: Port Enable/Disable Status Change
0 = No change has occurred on Port Enable/Disable Status
1 = Port Enable/Disable status has changed
Set by hardware due to babble, physical disconnect or overcurrent except for Port 1 in which
case it is set by hardware at EOF2 due to hardware events. Cleared by firmware via Host
request ClearPortFeature(PORT_ENABLE).
Bit 0 – PCSC: Port Connect Status Change
0 = No change has occurred on Current Connect Status
1 = Current Connect Status has changed
This bit is set by hardware at EOF2 after it detects a connect or disconnect at a port, except for
Port 1. Hardware sets this bit for Port 5 after a hub reset. Cleared by firmware via Host request
ClearPortFeature(PORT_CONNECTION).
