Two computers. One set of peripherals. But your new laptop has a USB-C port and the old one's got Type-A. Now you're hunting for adapters or buying a second mouse. The ATEN US3324 solves that in one box. Four USB devices shared between two machines at 5Gbps. Cables are bundled – Type-B to Type-A for your standard PCs, plus a Type-B to Type-C cable so your USB-C laptop plugs straight in. No extra cable run. External remote selector keeps switching simple. If you've got a mixed setup of old and new hardware, this is the cleanest way to share what you already own
