2. Omit the ganged mode pull-up resistor on 'SUSPND' pin.
3. Add a 10K pull-up resistor to 'RESET' pin.

Description
4. Connect pin 1 of U2 to B_VCC, then regulator will be enabled
only when upstream port is plugged!
A 1M pull-low resistor is also added to disable this pin when
the upstream port is not plugged.
1. Seperate 4-port and 7-port hubs into different schematic files.

5. 'SELF' is directly connected to drain of Q4 to omit the external
debounce RC circuit for this pin.
7. Some resistor values are increased to save the operating current.
6. Q1 is replaced by a more popular and cheaper one -- FDN340P.
1.2
1. Change the pull-up voltage source for each LED from B_VCC to power
switch output.
2. Remove the 47U output capacitor of MIC29302 to suppress inrush current.
3. Add R1, R2 and C6 for EMI suppressing.
4. Change C10, C15, C18 and C23 from 100U to 120U for better behavior in
droop test.
6. Remove a redudant transistor in SELF-BUS power switching circuit.
5. Add a 2-transistor circuit for regulator ENABLE pin. That will save
several tens of mA operating current than direct connecting B_VCC
to ENABLE pin.
