Hub Ports SE0 Status
Bit [0..3]: Port x SE0 Status (where x = 1..4)
Set to 1 if a SE0 is output on the Port x bus; Set to 0 if a Non-SE0
is output on the Port x bus.
Hub Ports Data
Bit [0..3]: Port x Diff Data (where x = 1..4)
Set to 1 if D+ > D– (forced differential 1, if signal is differential,
i.e. not a SE0 or SE1). Set to 0 if D– > D+ (forced differential 0,
if signal is differential, i.e., not a SE0 or SE1);
Downstream Port Suspend and Resume
The Hub Ports Suspend Register
Resume Status Register
resume conditions on downstream ports. The suspend register
must be set by firmware for any ports that are selectively
suspended. Also, this register is only valid for ports that are
selectively suspended.
If a port is marked as selectively suspended, normal USB traffic
is not sent to that port. Resume traffic is also prevented from
going to that port, unless the Resume comes from the selectively
suspended port. If a resume condition is detected on the port,
hardware reflects a Resume back to the port, sets the Resume
bit in the Hub Ports Resume Register, and generates a hub
interrupt. If a disconnect occurs on a port marked as selectively
suspended, the suspend bit is cleared.
Hub Ports Suspend
Bit [0..3]: Port x Selective Suspend (where x = 1..4)
Set to 1 if Port x is Selectively Suspended; Set to 0 if Port x Do
not suspend.

The Device Remote Wakeup bit (bit 7) of the Hub Ports Suspend
Register controls whether or not the resume signal is propagated
by the hub after a connect or a disconnect event. If the Device
Remote Wakeup bit is set, the hub automatically propagates the
resume signal after a connect or a disconnect event. If the
Device Remote Wakeup bit is cleared, the hub does not
propagate the resume signal. The setting of the Device Remote
Wakeup flag has no impact on the propagation of the resume
signal after a downstream remote wakeup event. The hub
automatically propagates the resume signal after a remote
wakeup event, regardless of the state of the Device Remote
wakeup bit. The state of this bit has no impact on the generation
of the hub interrupt. These registers are cleared on reset or USB
bus reset.
Bit 7: Device Remote Wakeup.
When set to 1, Enable hardware upstream resume signaling for
connect and disconnect events during global resume.
When set to 0, Disable hardware upstream resume signaling for
connect and disconnect events during global resume.
