Share four USB peripherals between four computers
4 computer inputs4 peripheral portsUSB 3.1 Gen 1Push-button selection
The TRENDnet TK-U404 is a switchable four-port USB hub for sharing compatible peripherals among up to four computers. Connect a keyboard, mouse, scanner or other supported USB devices, then use the push button to select the active computer. The selected computer controls the shared devices; they are not simultaneously connected to all four hosts.
Best For: Desks with several computers that need to share USB peripherals while keeping monitor connections separate.
Before you order: Use the supplied host cables and the labelled PC and DEVICE ports. This switch does not transfer files directly between computers or switch monitor video. Safely eject storage and finish device activity before changing hosts. The switch installs without its own driver, but each peripheral still needs operating-system support and any required driver.
What's in the Box
- TK-U404 and quick installation guide.
- Four USB 3.1 Gen 1 Type-A-to-Type-A computer connection cables.
- One Micro USB power cable. No external mains adapter is required for the switch.
What It Means in Practice
- Attach up to four computers to the PC ports using the included host cables.
- Connect up to four peripherals to the DEVICE ports: three are on the front and the fourth is on the opposite side.
- Press the selection button and use the LED to identify the active computer. Allow devices to reconnect after switching.
- Keep displays connected separately and use appropriate power for peripherals that require it.
What Will Not Work
- No HDMI, DisplayPort or monitor switching.
- No Ethernet switching or direct computer-to-computer data bridge.
- Only one selected host uses the shared devices at a time.
- No USB-C docking, Power Delivery charging or guaranteed support for every specialised USB peripheral.

Technical Specifications
Frequently Asked Questions
Singular Expert Insight
Check the distinction between a USB sharing switch and a video KVM. This model is useful when several computers already have display connections and need access to the same USB devices. Follow the host labels and eject removable storage before switching to avoid interrupting active work.
