Parameter
Hub Event Timings
Time to detect a downstream facing port
connect event (Figure 2-19):
Awake hub
Suspended hub
Time to detect a disconnect event at a
hub’s downstream facing port (Figure 2-18)
Duration of driving resume to a
downstream port (only from a controlling
hub)
Time from detecting downstream resume
to rebroadcast
Duration of driving reset to a downstream
facing port (Figure 2-20)
Time to detect a long K from upstream
Time to detect a long SE0 from upstream
Duration of repeating SE0 upstream (for
low-/full-speed repeater)
Inter-packet delay (for high-speed) of
packets traveling in same direction
Inter-packet delay (for high-speed) of
packets traveling in opposite direction
Inter-packet delay for device/root hub
response with detachable cable for high-
speed
Time of which a Chirp J or Chirp K must be
continuously detected (filtered) by hub or
device during Reset handshake
Time after end of device Chirp K by which
hub must start driving first Chirp K in the
hub’s chirp sequence
Time for which each individual Chirp J or
Chirp K in the chirp sequence is driven
downstream by hub during reset
Time before end of reset by which a hub
must end its downstream chirp sequence
Time from internal power good to device
pulling D+ beyond VIHZ (Figure 2-20)
Debounce interval provided by USB
system software after attach (Figure 2-20)
Maximum duration of suspend averaging
interval
Period of idle bus before device can initiate
resume
Duration of driving resume upstream
