So, no matter how many USB hubs you have lined up and connected, the single port that you have it plugged into will only be able to provide a total of 115MB/s per USB controller. It creates a bottleneck in the process, slowing the overall transfer rate to these devices proportionate to the demands of the devices attached to it. Therefore, the more peripheral devices you have connected to the USB hubs you have daisy chained to a single port, the lower the data transfer rate will be to those devices. This transfer rate remains constant, regardless of the number of devices you have attached to the computer. This data rate holds true for each USB controller on the motherboard. The maximum rate at which data can be transferred via a USB 3.0 connection is around 115Mb/s.

A select few devices, like high speed external hard drives, will require more power than a single USB hub port can provide.

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'.
