The SMSC Hub monitors VBUS_DET to determine when to assert the internal D+ pull-up resistor (signalling a connect event). When designing a detachable hub, this pin must be connected to the VBUS power pin of the USB port that is upstream of the hub.

    5.1.1 Hub Configuration Options The SMSC Hub supports a large number of features and must be configured in order to correctly function when attached to a USB host controller. There are three principal ways to configure the hub: SMBus, EEPROM, or by internal default settings. In all cases, the configuration method will be determined by the CFG_SEL1 and CFG_SEL0 pins immediately after RESET_N negation.
  • Page 16 This field is set by the OEM using either the SMBus or EEPROM interface options. Note: When configured via strapping options, declaring a port as non-removable automatically causes the hub controller to report that it is part of a compound device.
