Single Keyboard, Multiple PCs, Easy Choice.
Color: Black
Device is small, blends in well with my desk and other peripherals. It was easy to setup. No additional power source needed. It powers up with the USB cables it came with. I have it plugged into 2 PCs, 1 gaming and 1 daily PC. The only thing i have hooked up to the device is a Logitech G915 X Gaming Keyboard and i cannot complain. While playing games, the responsiveness is still there. There is no lag or anything. Love the remove it came with, im able to switch between PCs at a click of a button and it's almost instant. Im sure it can handle other devices as well. Compared to other switches, this was a good price point with the extra ports that other USB Switches dont have. The device feels sturdy and well made. ... show more

Fails as soon as a USB camera or microphone shares the switch with another device
Color: Black
I purchased this UGREEN USB 3.0 switch specifically to share an OBSBOT Tiny 2 Lite webcam and an Elgato Wave:3 microphone between two computers. Based on the listing, it appeared perfect for this use: four USB ports, 5 Gbps USB 3.0, optional external power, and explicit support for USB cameras and headsets. Unfortunately, it cannot reliably handle the advertised use case. My Windows 11 computer has a Gigabyte B650M H Rev. 1.0 motherboard. I connected the UGREEN switch directly to a rear USB 3.2 Gen 1 port, not through another hub or a front-panel connection. I also powered the switch using a 5 V/2 A adapter, which exactly matches the specification in the included manual. For troubleshooting, I additionally tested it with an official Raspberry Pi 4 power supply capable of providing 5.1 V/3 A. External power made no difference. The webcam and microphone work perfectly when connected directly to the motherboard’s USB ports, including when both are used simultaneously. Each device also works individually through the UGREEN switch. However, as soon as either the webcam or microphone shares the switch with any other peripheral—even something as basic as a mouse or keyboard—Windows displays the error “Not enough USB controller resources,” and the devices do not function correctly. This rules out a problem with the computer, webcam, microphone, or insufficient power. The failure only appears when multiple devices are connected through this switch. It may work for switching a single device or perhaps a basic keyboard and mouse, but that is not why I purchased a four-port powered USB 3.0 switch. The listing specifically mentions sharing multiple devices, USB cameras, and headsets, yet my unit cannot handle a camera or USB microphone alongside even one simple peripheral. This was extremely disappointing, especially after carefully following the product specifications and testing multiple power supplies and connection arrangements. I cannot recommend it to anyone intending to share a webcam, USB microphone, or other composite USB device between computers. ... show more

KVM for Two Computers
Color: Black
The UGREEN USB 3.0 Switch is an excellent solution if you need to share USB devices—like a keyboard, mouse, printer, scanner, or even a USB-C accessory—between two separate computers. It’s designed to streamline desk setups, reduce cable clutter, and make switching between devices as simple as pushing a button (or using the included remote controller). Below are the key highlights from my experience. Design & Build Quality Compact & Sturdy: The switch has a small, rectangular form factor with a matte black finish, which fits discreetly on a desk or can be tucked away. Port Arrangement: On one side, you’ll find two USB 3.0 Type-B ports (for connecting to the computers) and a micro-USB power input (if extra power is needed for high-power devices). On the opposite side are four USB 3.0 Type-A ports and one Type-C port for your peripherals. LED Indicators: Each computer input has a corresponding LED light to show which system is currently connected—helpful for a quick visual check. Setup & Installation Plug-and-Play: No drivers are needed. Simply connect the two included USB 3.0 cables from the switch to each computer. Connect Peripherals: Attach up to four devices (plus the USB-C device) to the switch’s output ports. Power Considerations: If you’re using power-hungry accessories (like external hard drives), you may want to use the optional micro-USB power input to ensure stable performance. Immediate Recognition: Both Windows and macOS recognized the connected peripherals instantly when toggling the switch. Performance USB 3.0 Speeds: The switch supports data transfer rates up to 5 Gbps, so file transfers to and from external storage devices are quick. Smooth Switching: Toggling between computers is near-instant. I tested it with a keyboard, mouse, and an external HDD, and they reconnected without delay or dropped signals. Stable Connection: Even during extended use, the switch reliably maintained connections without random disconnects. Included Remote Controller Convenient Switching: Besides the on-device button, UGREEN provides a small external button (or “controller”) on a short cable. This allows you to position a toggle button within easy reach—handy if you prefer hiding the main switch unit behind a monitor or under a desk. Simple Layout: One push toggles the active computer, and the LEDs on the main unit still indicate the current selection. Use Cases Home Office: Seamlessly switch a single keyboard/mouse combo between a work laptop and a personal desktop. Shared Printer/Scanner: Perfect for small office scenarios where two users or two machines need to share a single printer or scanner. Multimedia & Testing: If you frequently switch devices between a PC and a gaming laptop (or a NAS box), having a quick toggle is a big timesaver. Pros & Cons Pros Easy Setup & Driverless Operation: Truly plug-and-play on both Windows and macOS. Fast USB 3.0 Transfer: Up to 5 Gbps speeds for transferring data or streaming from external drives. Multiple Ports & Type-C Support: Allows for up to four USB-A peripherals plus a USB-C device to be shared. Remote Switch/Controller: Makes switching inputs convenient if you mount the main unit out of sight. Stable & Reliable: Connections are consistent, with no random resets. Cons External Power May Be Required: High-draw devices (especially multiple HDDs) might need the extra micro-USB power input to ensure stable operation. Limited to Two Computers: It’s designed only for dual-computer setups; not expandable beyond that. Short Included Cables: The two USB 3.0 cables supplied are decent in length for most setups but might be short if your PCs are placed far apart. Final Thoughts For anyone juggling two computers but wanting to share the same USB peripherals, the UGREEN USB 3.0 Switch offers a clean and efficient solution. Its quick switching, reliable USB 3.0 speeds, and hassle-free installation make it a go-to accessory for streamlined workflows. Adding in the remote controller is a thoughtful touch—ensuring you don’t have to reach around cables or monitors to toggle devices. Highly recommended if you’re looking for a tidy, flexible way to share your keyboard, mouse, and other USB gadgets between two computers. ... show more

Reliable Workstation Switch for Dual-Setup Management
Color: Black
The Pros: Seamless Setup Management: This switch is exactly what I needed to maintain one workstation for both my personal and work environments. It handles my keyboard, mouse, and mic perfectly, making the transition between computers very easy. UGREEN Reliability: I find myself buying a lot of UGREEN products lately, and this one is no different. The price is great and the physical build quality is consistently high. Compact Design: It has a small footprint on the desk, which helps keep the workstation looking clean and organized despite having multiple cables plugged in. The Cons: Connection Handshake: Since the device physically disconnects and reconnects the peripherals when you switch, the computer can occasionally act a bit weird. I did have one instance where the mouse would move but clicking didn't work until a reboot. Lack of Emulation: It would be ideal if the device kept the connection active on both computers at all times rather than fully disconnecting. This would likely prevent that occasional lag or "re-learning" the PC goes through during the switch. Bottom Line: Overall, this is a solid and affordable solution for anyone running a dual-computer setup. Despite the occasional minor handshake issue, it is a high-quality piece of gear that makes managing a hybrid workspace much more convenient. ... show more

Reliable and Easy to Use
Color: Black
I recently purchased the UGREEN USB 3.0 Switch 2 to replace a faulty switch in my setup. The next-day delivery was impressive, and I had it up and running within minutes. The setup was straightforward, and I didn't even need to consult the manual. The build quality is solid and feels durable. A standout feature is the wired remote switch, which allows me to toggle between computers without having to reach for the main unit. So far, the switch has performed reliably, seamlessly managing my peripherals (mechanical keyboard, wireless mouse, and a mic) between two computers. If there's one thing to gripe, it'd be the indicator LEDs for Computer A & B, which are placed close together, making it difficult to know which computer is connected. ... show more

Great little switch so far but not perfect for everything
Color: Black
Review Image by Yousef Mohamed
I purchased this switch as I got a new job working from home so I wanted to experiment with using the same set of perphirals for both my work & personal PC as I haven't decided on setting up an extra keyboard/getting a keyboard tray. This was a good time to buy since this is supposed to upgrade the very popular 4-USB3 switch Ugreen has been selling for a few years now and I feel like this is a warranted upgrade. Overall this switch has worked almost flawlessly in my week of use. I have plugged into it my Hyperx 60 keyboard and all the lights & effects/settings I set up still work when plugged in, a G703 mouse and my Logitech C920 camera outputting to my personal desktop and my work laptop. I have tried it both with and without the extra USB C power "boost" and while everything works I think my mouse drains a little quicker (maybe using more battery since the switch isn't meeting 100% power?? might have to test more) but the keyboard and webcam seem to have no issues, I generally do keep a usbc plugged in though just in case. Latency hasnt really been a problem, I tried a mouse latency site with my mouse plugged into my PC and the switch and they both were pretty much the same (and low) which is honestly important for me as I am a big gamer so making sure lag is minimzed is a priority. The only real issue I have had was that I tried using my headphones plugged into the Apple 3.5mm to USBC dongle inputting into the switch and about every 30-40 mins I would get absolutely AWFUL static and noise and it didnt matter how I oriented the dongle so Im guessing there mightve been some interference between the dongle and switch. Overall I'd recommend this as it's great for minimizing desk clutter without compromising performance and it's very affordable at around $35, which is in line with the previous model when it was the main one. It also comes with a little "remote" extension sol you can put the switch somewhere and then have the remote button in a more convenient spot if you're swapping a lot; I haven't used it but it is a nice addition. I wish there was a 3.5mm jack input even if it meant the model being a little larger but this is pretty much a solid buy for anyone WFH or using multiple computers. ... show more

Great Potential - Depends on Your Peripherals
Color: Black
Purchased this to switch between a work laptop and personal gaming desktop. I was going to go with Ugreen's older model, but I specifically wanted the wired 'remote' (in case I ever decide to tuck it out of sight) and the USB-C power adapter (instead of Micro USB). I'm only aware of a single Thunderbolt 4 KVM on the market (Sabrent) and I wasn't trying to spend that much money. Known limitations of full KVM's / switchers are lack of VRR and other gaming oriented features, so I decided on only USB to accommodate mouse, keyboard, webcam, and DAC/AMP. It works great most of the time, but if your devices rely on software it gets iffy. I don't own any other USB switchers to do A/B comparisons, so I can't confirm whether it's this device specifically or the other devices / software. Nonetheless, this has problems with Roccat (keyboard & mouse) and sometimes Razer (webcam). The webcam either will or won't be detected; if it's detected it works, otherwise it doesn't. The Roccat devices will work, but have disconnection / stuttering issues. It's frequent, but not consistent. Every 3-4 minutes the mouse and keyboard will stop functioning for ~5 seconds, and then when they are recognized again the keyboard will repeat the last key pressed about 3 dozen times before it's back to normal. For casual use you may never notice this, but when playing video games you definitely will. I've been 'frozen' in a gunfight (running uncontrollably in whatever WASD direction I was pressing), I've unintentionally ran off the edges of the world, I've tried jumping only to fall to my death, etc. Because it's not registering input, you can't just use Escape to pause either. It doesn't have a pattern, but it's frequent and it's frustrating. The problem persists while the software is running and even after I've closed it out. The problem persists through PC restarts. The problem persists using different USB headers on my motherboard and case. The problem persists even if I disconnect the 2nd computer from the switch. On a positive note, this has worked flawlessly with a Logitech C925-E Webcam, a Glorious Model O Minus, a GMMK, various flash drives, and with a few SD card readers. The device itself is sleek, comes with cables, and imo looks nice. Unfortunately, it's a tough recommendation based on the devices you own. If you're not a gamer, it's most likely a recommendation. But if you do have gaming peripherals you might want to look elsewhere. ... show more
