5.2.3 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 3A. If the
connected device does not comply with BC1.2, the charge current will be limited to 900 mA in
compliance with USB specifications.
If you wish to limit the charging to your devices whilst connected to your host system then you can
disable CDP. You can disable CDP through NVRAM settings either by going through the advanced
settings and turning "Sync charge" off or through the API and disabling it via code. For example, the
instructions would be below using the command line.
The CLI commands for turning off the sync charge options, with a 1 or 0 per port.
settings_unlock
settings_reset
settings_set sync_chrg 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
settings_set alt_sync_chrg 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
reboot
This can also be done via the API if this is easier. Just supply that string (joined with \n) like:
cbrxapi.cbrx_connection_set(handle, "settings", "settings_unlock\nsettings_reset\n-
settings_set sync_chrg 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0\nsettings_set alt_sync_chrg 0
0 0 0 0 0 0 0 0 0 0 0 0 0 0 0\nreboot")
Note that settings_reset clears any previous settings, so if you need to retain something else, it would
be better to issue settings_display first, which gives you the entire settings which you can then
modify and re-issue in entirity.
5.2.4 Data Transfer
If you wish to transfer data, change applications, restore or update your mobile device, a data
connection to a local host computer is required. The hub is compatible with macOS®, Windows™ and
Linux® operating systems and can transfer data between these operating systems and many mobile
operating systems such as iOS™ and Android™.
In order to transfer data, connect the host port to your local (host) computer using a Thunderbolt™ 3
compliant cable. Any devices connected to the hub will now appear as if they were connected to the
host computer’s USB port.
In order to transfer data, connect the Thunderbolt™ port of your local (host) computer to one of the
Thunderbolt™ ports on the back of the hub using a Thunderbolt™ 3 compliant cable. A Thunderbolt™
2 cable with a Thunderbolt™ 2-3 adaptor can also be used with consequently reduced data speeds.
Any devices connected to the hub will now appear as if they were connected to the host computer’s
USB port. The hub is fully compliant with SuperSpeed USB3.2 and can provide up to 5Gbps data
