BFKK USB 3.0 KVM Switcher 2 Computers 4 Ports PC Mouse Keyboard Printer

Two-computer four-port USB 3.0 KVM

This BFKK KVM switch lets two computers share four USB 3.0 peripherals such as keyboards, mice, flash drives, printers and scanners. It removes the need to unplug cables or configure network sharing software, freeing desk space and streamlining workflow. The device is driver-free and works with Windows, Mac, Linux and Chrome OS. A single button with LED indication toggles the active computer instantly.

Sustained 5 Gbps throughput across four ports

Each of the four ports supports USB 3.0 data rates up to 5 Gbps, maintaining that speed during extended file transfers or continuous peripheral use rather than only in short bursts. The switch is backward compatible with USB 2.0 and USB 1.1 devices, so older peripherals remain functional without degrading the performance of newer ones. No external power adapter is mentioned, so the unit draws power from the connected computers.

Driver-free setup with one-button switching

Installation is plug-and-play: connect the switch to both computers and attach peripherals, then press the button to change control. Green and blue LEDs show which system is active, eliminating guesswork. The only common issue is ensuring both host machines supply enough bus power for high-draw devices; if a peripheral exceeds the available current it may disconnect until power is restored.
