Scalability
If you wish to synchronise more devices, multiple hubs can be connected to allow more devices
to be managed from a single host computer simultaneously
.
To daisy-chain multiple hubs, each hub needs to be connected to mains power
individually, and the first hub in the chain should be connected to the local computer through
the hub’s “host port”. The host port of the next hub in the daisy-chain is then connected to any
of the first hub's downstream USB ports. More hubs are added in the same way
.
Using this daisy-chain approach, a maximum of four additional hubs can be linked, allowing a
total of 71 devices to be synced from a single host computer. Alternatively, a star topology can
be used, which allows up to 85 devices to be synced from a single computer. In this
arrangement, the first hub is attached in the same way, connecting the hubs host port to the
computer’s USB port. After that, five additional hubs can be attached to the downstream USB
ports of the first hubs by their host ports as shown below
.
