Please stop treating your USB hubs as port replicators
It's not quite the same
The article advises against treating USB hubs as replacement for port replicators. While USB hubs can be useful for adding extra ports to a laptop, they have limitations that can impact device performance. One major issue is that the connection from the hub to the computer is often the same USB connection used by each peripheral, limiting the overall bandwidth available.
This means multiple high-speed devices connected to the hub may fight for bandwidth, slowing everything down. Even if the hub is not fully utilized, the added step of data processing by the USB hub can introduce latency, causing delays in audio or video streams. The article shares a personal experience with a capture card and livestreaming, where the USB hub caused video output to pause multiple times.
Another limitation is power supply. USB hubs can only provide up to 15W to peripherals by default, which may not be enough for power-hungry devices like audio interfaces. Thunderbolt docks offer a more reliable solution with higher bandwidth and better power management, but they also have their own limitations in terms of the number of connected devices and external power requirements.
The ideal solution would be for laptops to have more ports built-in, but for now, users should be cautious when relying on USB hubs for critical workflows.
