Active LOW Reset
. This pin resets the entire chip. It is normally tied to V
CC
through a 100K resistor, and to GND through a 0.1-μF capacitor. Other than
this, no other special power-up procedure is required.
VBUS
. Connect to the VBUS pin of the upstream connector. This signal
indicates to the hub that it is in a powered state, and may enable the D+ pull-up
resistor to indicate a connection. (The hub will do so after the external
EEPROM is read, unless it is put into a high-speed mode by the upstream
hub). The hub can not be bus powered, and the VBUS signal must not be
used as a power source.
