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.
