5. Using your U8S
In this section, you can find information using your hub in a charge only or a charge and sync
application. You can also find information on managing your hub, changing port modes,
connecting multiple hubs to one host and using Cambrionix Software.
5.1. Using without connecting to host
When the Hub is switched on and is not connected to a local host computer it is
automatically configured to charge devices using its intelligent charging algorithm. Connect the
devices to be charged to any of the available ports (not the Host Port) using
USB - compliant cables.
Once the devices are connected, the algorithm will detect the highest charge rate allowable for
each attached device. Charging at the optimum rate (up to 2.1A) specified by the manufacturer
will commence once profiling is complete. Depending on the state of charge of the device
attached, this may take tens of seconds.
5.2. Using when connected to host
5.2.1 Connecting the Hub to a host computer
Connect the U8S to your host system using a USB 2.0 Type-B cable. Using an incorrect host
cable may result in the hub and all subsequent ports not being recognised by your host.
5.2.2 Charging
When the Host Port is connected to a local computer, the hub defaults to Sync mode and
charge currents are determined according to USB Implementers Forum (USBIF) Super-Speed
USB3 specifications. If the attached device complies with USB-IF Battery Charging
specification BC1.2 and supports Charging Downstream Port (CDP), the hub can provide
high-speed charging at 2.1A. If the connected device does not comply with BC1.2, the charge
current will be limited to 500 mA in compliance with USB specifications.
