2.5 Operation
The SiP VoIP and PoE Speaker is a standard USB Hub that complies with the USB 2.0 specification, 
and adds PoweredUSB ports. When connected to a Host, it is enumerated as a Generic USB Hub. This 
Hub also meets the PoweredUSB .08g specification. For more information about this specification, 
go to www.poweredusb.org.
POS peripheral 
caveat
According to the USB 2.0 specification, devices attached to a USB interface should enumerate from 
the Hub’s USB Vbus, regardless of the PoweredUSB powered ports. Some POS devices do not 
comply with this specification, and will not enumerate unless the upper sections of the PoweredUSB 
ports are active.
