Manging Ports and Devices

Managing Ports & Your SuperSync15

Each port on your SuperSync15 can be managed either individually, or all together. You can turn the ports off and on, change the port mode, or change various other settings applicable to the SuperSync15. This can be done through Cambrionix Connect, the CLI or by connecting to the hub via the API.

Port Modes

Table 5-35

Charge	Turn specific ports or the whole hub to charge only mode (no data connection, hub emulates an OEM charger)
Sync	Turn specific ports or the whole hub to sync mode
Biased	Detect the presence of a device but it will not sync or charge it
Off	Turn specific ports on or off or switch the whole hub on or off (no power and no data channels open, mimics unplugging the device)

Switching port modes

You can switch between port modes by using Cambrionix Connect, the CLI or by connecting to the hub via the API. If you switch a port off then this will stop any connection taking place to the USB device and would mimic unplugging the USB device completely from the host system.

If you are in Sync mode and then switch to Charge mode the USB device will disconnect briefly whilst the profiling process takes place, during the profiling process the connection will disconnect and reconnect whilst the device settles on the optimum profile. Once the profiling has taken place, and a charging profile is selected, the device will then draw a charge rate, which will be defined by the charging controller within the USB device. The charging profile will limit the maximum amount that the device is able to draw.

If you are in Off or Charge mode and switch to Sync mode the USB device will disconnect briefly whilst a data connection is opened, the USB device will then become available to the host as if the USB device is connected directly to the host, and will be able to sync data. The SuperSync15 will also charge the device whilst connected. It is impossible to have a data connection to a USB device without any power negotiating, you can reduce the charging rates available by disabling CDP (Charging downstream port).

Charging Profiles

To ensure attached devices charge at their optimum rate, our smart USB hubs come with the below intelligent charging profiles built in:

Table 5-36

0	Intelligent charging algorithm which will select a profile 1-6
1	2.1A (Apple)
2	BC1.2 Standard (this covers the majority of Android™ phones and other devices)
3	Samsung
4	2.1A (Profile 1 but with a longer timeout)
5	1.0A (Typically used by Apple)
6	2.4A (Typically used by Apple)
