• Enable - This method enables the USB HUB device.
  
  ANSIC prototype: byte Enable(void)
  
  • Return value:byte - Error code, possible codes:
    ERR_OK - OK
    ERR_SPEED - This device does not work in the active speed mode.
  
  
• Disable - This method disables the USB HUB device. Because this HUB has no internal pull-up on D0+ and external pull-up must be used. Before disabling the device this pull-up should be disconnect.
  
  ANSIC prototype: byte Disable(void)
  
  • Return value:byte - Error code, possible codes:
    ERR_OK - OK
    ERR_SPEED - This device does not work in the active speed mode.
  
  
• EnableEvent - Enable the events.
  
  ANSIC prototype: byte EnableEvent(void)
  
  • Return value:byte - Error code, possible codes:
    ERR_OK - OK
    ERR_SPEED - This device does not work in the active speed mode
  
  
• DisableEvent - Disable the events.
  
  ANSIC prototype: byte DisableEvent(void)
  
  • Return value:byte - Error code, possible codes:
    ERR_OK - OK
    ERR_SPEED - This device does not work in the active speed mode
  
  
• LocalPowerSourceChange - This method must be called when state of local (external) power source of the hub has been changed.
  
  ANSIC prototype: byte LocalPowerSourceChange(bool LocalPowerSource)
  
  • LocalPowerSource:bool - true - local power supply is good, false - local power supply lost (inactiv)
  • Return value:byte - Error code, possible codes:
    ERR_OK - OK.
    ERR_SPEED - This device does not work in the active speed mode.
    ERR_DISABLED - Device is disabled.
  
  
• PortOvercurrent - This function must be called when the over-current on the port is detected or when the over-current on the port stop.
  
  ANSIC prototype: byte PortOvercurrent(bool Overcurrent, byte Port)
  
  • Overcurrent:bool - Set to true if over-current is detected, set to false after over-current stop.
  • Port:byte - Number of port to change over-current state.
  • Return value:byte - Error code, possible codes:
    ERR_OK - OK.
    ERR_SPEED - This device does not work in the active speed mode.
    ERR_DISABLED - Device is disabled.
  
  
• HubOvercurrent - This function is called to report hub's over-current state if the hub has only one power switch (Ganged power switching mode).
  
  ANSIC prototype: byte HubOvercurrent(bool Overcurrent)
  
  • Overcurrent:bool - Set to true if over-current is detected, set to false after over-current end.
  • Return value:byte - Error code, possible codes:
    ERR_OK - OK.
    ERR_SPEED - This device does not work in the active speed mode.
    ERR_DISABLED - Device is disabled.
