usb hubs

USB hubs are a practical way to add ports to a desktop PC when the existing connections are used up. The tagged discussion covers the main options: an external hub, a monitor's built-in USB hub, a PCIe expansion card, or routing unused motherboard headers to accessible sockets. The key point is matching the method to the workload, since a keyboard and mouse need far less bandwidth and power than several devices moving large amounts of data. Advertised hub speeds also apply to the upstream connection, so shared bandwidth matters when several peripherals are active at once.
