Should I worry about USB hub interference in a mousepad with wireless gear?

Yes — a built-in USB hub reduces desk clutter but can cause signal interference with 2.4GHz wireless mice or keyboards. USB 3.0 ports emit radio noise in the 2.4GHz band, leading to stutter, lag, or disconnects. The workaround is to keep the dongle plugged directly into your PC or use wired devices. It’s a good clutter fix as long as you don’t expect the hub to play nice with sensitive wireless peripherals.
