![]() Most devices will not require the full power load that these ports make available, but there are several devices that will make use of all of the power this connection facilitates. Most USB devices draw power from the ports they are connected to, receiving at most 5.25V from a single port the same is true for ports made available by USB hubs. ![]() We've assembled a few key points to remember when connecting powered USB hubs to your devices, or to each other. However, this process raises a few important concerns that mean we simply can't recommend daisy chaining as any kind of permanent solution. Frequently, as many as 127 devices can be hooked up to a computer via a single daisy chain of USB hubs. This can be a viable solution when several USB ports are needed and many manufacturers list the maximum number of ports that can be made available with this method when using their hubs. When a user needs more USB ports than can be found in a single USB hub, they will often connect multiple hubs together in a process colloquially known as 'daisy chaining'.
