We are applying  TUSB2046B as figure13 page15 on the datasheet to our system circuitry.

Questions are,

1)While the system power up with USB cables connected into all 4 ports(DM1/DP1~DM4/DP4).

  How about the USB bus power up turn for 4 ports(DM1/DP1→DM2/DP2.......)

2)How about the USB Hand-Shake process complition turn for 4 ports?

   (DM1/DP1→DM2/DP2.......)

Regards,
