5.1.8

HUB CONNECT STAGE (HUB.CONNECT)

Once the CHGDET stage is completed, the device enters the Hub Connect stage. USB connect can be initiated by

asserting the VBUS pin function high. The device will remain in the Hub Connect stage indefinitely until the VBUS pin

function is deasserted.

5.1.9

NORMAL MODE

Lastly, the hub enters Normal Mode of operation. In this stage full USB operation is supported under control of the USB

Host on the upstream port. The device will remain in the normal mode until the operating mode is changed by the sys-

tem.

If RESET_N is asserted low, then Standby Mode is entered. The device may then be placed into any of the designated

hub stages. Asserting a soft disconnect on the upstream port will cause the hub to return to the Hub.Connect stage until

the soft disconnect is negated.
