I'm curious about whether connecting a USB hub to my PC will affect the performance of devices I plug into it. If I connect things like my Bluetooth mouse, wired keyboard, and an audio interface to a hub, could that lead to any performance issues? I'm not really clear on how much data can be effectively transferred through a single USB port.

For a Bluetooth mouse, the performance impact is usually minimal. If you are worried about latency, it might depend more on the dongle than the hub itself. Most devices like keyboards and audio interfaces don't require much bandwidth.
It really depends, but generally speaking, using a USB hub has a negligible impact unless you're maxing out the bandwidth on a device for data-heavy applications. For basic peripherals like keyboards and mice, you should be fine!
Investing in a USB4 hub (40Gbps) or a USB 3.2 hub (10Gbps) is a great idea if you're looking for top performance. That way, you'll have plenty of bandwidth available for anything you connect.
If you're mainly connecting a keyboard, mouse, stream deck, and audio interface, you shouldn’t see any major performance drops. These devices operate on low power and usually work just fine over USB 2.0.
