USB 3.0 Switch

Update: 12/2/2021 I have been using this switch for nearly 3 years, switching between personal and work computers every single weekday, sometimes multiple times a day in that time, as well as moving it to a new desk setup, and it has worked and continues to work flawlessly. I am very pleased with this device and cannot recommend it highly enough, even if it were to fail tomorrow. Original Review: I set up a docking station for my work laptop at my home office desk where I also use my personal computer. I quickly realized that swapping USB adapters for mouse and keyboard every time I wanted to switch between work and personal computers was a hassle and unnecessary wear and tear on the ports. Once I also realized that the built-in DAC in my work laptop was garbage when I was trying to listen to some music on Pandora while I worked, I decided to look for a USB switch and came across this one. I am happy to report that the UGREEN USB 3.0 switch works almost perfectly with my setup. I have it connected to my personal computer and my laptop dock. Plugged into the front, I have my mouse adapter, wired keyboard, and a standalone DAC. I even used the 4th USB port for another keyboard adapter so that I can use my wireless keyboard from my couch when I want to switch the computer display over to my TV, and this works great as well. Pressing the button on top of the UGREEN unit quickly switches control from one computer to another with no delay. A small, non-intrusive blue LED indicates which computer is active. Mouse, keyboard, and the audio DAC all immediately work correctly on the selected computer. The only thing that I sometimes have issues with is if the computer I am switching to is asleep. In that case, moving the mouse or pushing a key on the keyboard does not wake up the computer like it normally would, and I have to press the power button on the computer to wake it up. I'm not sure why this happens but it seems like if the USB connection was not active when the computer was put to sleep, it does not make the connection until it is manually woken up. I have checked in my power settings to make sure that USB ports are not turned off when the computer is asleep, as this would be an obvious cause for the issue, but that is not the case. This is a minor inconvenience since my personal computer and dock power buttons are both easily accessible, but would be nice if it worked. The UGREEN unit is quite small and sits inconspicuously on my desk on top of my audio mixer. To keep the cables managed cleanly I do have to make a 180 degree bend with my two wired connections (keyboard and DAC) to route the cables back behind the switch. If I just had 4 USB adapters plugged in, that wouldn't be an issue. The only way to fix this would be to have all the ports on the back, and then the unit would have to be larger in size to accommodate 6 ports on one side instead of 4. The switch is very lightweight (which means stiff cords sometimes lift it so it doesn't sit flat) and has a cheap feeling plastic housing with no mounting provision if you wanted to attach it to something, but these are minor complaints as it works well enough. It appears you can power the switch with micro USB if your devices require a lot of power (if you were wanting to charge something via USB for example), but even with the backlit keyboard I am using, I do not have this switch connected to power, and it and my devices work just fine. Overall I am happy with the UGREEN USB 3.0 switch. If it were able to always make a connection with a computer that is asleep when switched to, I would be even happier, but that may not even be the fault of the switch. I definitely recommend this if you are looking to share inputs between two computers without having to plug and unplug cords, dongles and adapters.

I own three of these already. That's how much I love them. These work really great. They can be powered by a microUSB cable plugged into a separate charging port, or they can be charged by the USB bus of either computer they're connected to. All three of mine are not connected to power via the microUSB port and they all work flawlessly. Here's the way I use all three of mine, in case anyone's wondering. I have 4 computers. Two Windows 10 PCs, and two Macbook Pros. Well one of the MBPs is a company machine. I have a UGREEN KVM on the left, one in the middle and one on the right. I'm a streamer so I have a 2 PC setup, a gaming PC and a stream PC. I'm left handed so I have the mouse on the left side of my keyboard, for gaming but I also use a Magic Trackpad on the right to control the Macs. I've always been ambidextrous with pointing devices but prefer the mouse on the left for gaming. The keyboard is plugged into the center KVM. The mouse (along with the center KVM) is plugged into the left KVM. The Magic Trackpad (along with the center KVM) is plugged into the right KVM. The left KVM switches the mouse and center KVM between the gaming and stream PC. The KVM on the right switches the Magic Trackpad and the center KVM between my home Macbook Pro and my company's Macbook Pro. The center KVM switches the keyboard between the PC side or the Mac side. So I can use the same keyboard with all four machines, and since the PC and Macs have their own dedicated pointed devices on different sides of the keyboard, this works very well for me. I have a Magic Keyboard I was using with the Macs when I had only two UGREEN KVMs but my desk was way too cluttered and it was a pain to find space for both keyboards. Now I only need one keyboard and I can easily control everything. These are great products. Even if I had a 4 computer KVM I would never be able to so easily switch between two the way I do now, but I suppose a possible con is that these only come in the 2 computer (and maybe 3 computer?) variety but not 4. Another thing that I'd like to see UGREEN improve on is putting the USB inputs on the back. Having them on the front is a bit of an eye sore and a pain, you can see in the pics the one on the right is lifted off the table at a diagonal angle due to the cables in the front being forced to turn around and go to the back, but it's not a big issue. Also one of the biggest headaches of not being allowed to work using my personal computer has been how to do it. For the longest time I was swapping out cables etc. with the Macs and occasionally glitches would arise, I'd have to reboot the computer, etc. It was a hassle. Now it's easy peasie, thanks to UGREEN! Thank you UGREEN!

Recently bought this to use for my gaming + secondary pc setup so i can share my keyboard and mouse between them as thus far it functions amazingly and works well by switching between the 2 setups at fast speeds as it takes like 1 second to switch after pressing the button which is awesome, I know that i spent a little extra for the usb 3.0 version in which for a future proof/utility usage i wanted to buy once and cry once that way if for some reason i need to i can have high data speeds between the computers, The reason why i gave a 4/5 is due to the cables when packaged are proper and are ok... The only issue with them is since it all fits like a tetris form fitting package the included usb 3.0 cables for connecting to the 2 computers have major kinks in them due to the turning of the cables within the bundle as i have remedied it by using my hands and after unraveling the cables carefully i let gravity to stretch them out a little bit so they are a little used to stretching then i grabbed one side of the cable holding it firm with my hand so that when i pull the cable through it safely unkinks the cable about 75% as you should go slow with it so it doesnt risk breaking as the slower the better just not fast!! Besides that it functions great and works properly even after testing on a triple monitor setup with switching between them... PS: This is a 1 Day Review and Thus Cannot Speak for Durability nor Long Usage but the Form is Awesome and Organizable to My Setup!!

I bought this to link a mouse, keyboard, audio interface, and powered usb hub to two different computers that are used for different purposes at different times. It's great. I've been using it for about a month or more now, and haven't had any issues at all so far. The two USB 3.0 cables that it comes with are very sturdy and have excellent bandwidth. I'm kind of confused by reviews complaining about the quality of the cables, they're high quality. Tested each and I get full data transfer speeds. The button switch eventually wearing out is my main concern, but it feels like a pretty solid button. I don't have a camera to test, but with the full USB 3.0 speeds it should be fine as long as your camera doesn't need more bandwidth than that. If so, you should probably looks elsewhere in the first place. I do suggest using a micro USB to supply power directly to the switch hub.

This works great! Imagine this as the "K" and "M" of KVM. It's literally that simple. My personal setup involves two ultra-wide monitors stacked one above the other. One has my work laptop plugged into it, and the lower one is for my desktop. I know that there is software available that can share a single mouse and keyboard, but it would always act up when I took my laptop out of the house, or would still function when I was working on my laptop solely, or would prevent my computer games from working when my mouse would leave the game and travel to my laptop! So after a few months of having my mouse and keyboard plugged into a usb 4-port thing and manually moving them to each system, I found this device and ordered it. It arriveded much quicker than I was expecting. As I mentioned in my title, it's much smaller than I was expecting. It's about 2 inched deep and about 4 inches wide (and about half an inch tall). Came with all the cables needed. I plugged in, connected to both systems just fine, and I haven't had an issue. I am now using it between a Mac Mini and my Windows Desktop, and It's handling everything perfectly. I have the mouse, keyboard, an external SSD, and a large powered 4TB backup disk all running through the one cable, and it's working exactly as I had expected. So great! My only suggestion for improvement is the switching time is not instant, and takes about 2 seconds to disconnect from one system and then have the devices recognized on the other. That could be my computers, or just USB devices themselves, but hey it's better than doing it myself. To me, the best kind of hardware is hardware that does it's job so well that you don't even notice because you are focus on the project at hand. and this definitely falls into that category for me. it works, it's quiet, and it's inexpensive. If you are wavering, i'd definitely recommend this device.

I did a lot of research and ordered a few units to test, this is the keeper! I had many questions prior to pulling the trigger and maybe my long-winded review will help someone else out there... SETUP: I am a gamer and a creative. I have my gaming PC hooked up to a 48" LG OLED. I recently added a Mac Mini to the setup as the "flagship" M2 Pro Mini FINALLY has HDMI 2.1 support (4K/120Hz @ 4.4.4. 10 Bit). I am also a custom mechanical keyboard collector FREAK. I didn't want to have to keep switching keyboard/mouse each time I swapped from my PC to my new Mac but I also wanted to make sure that a cheap USB switcher didn't fry my VERY expensive keyboards or computers! I did sooooo much research and landed on this unit and a 4 usb/4 PC StarTech unit. Well, I cancelled the StarTech as it was triple the cost, I only needed it for 2 PCs and this one works fantastic! I also asked around the keyboard community and people brought up this UGREEN unit time and time again... POWER: Because of my very expensive keyboard habit I was VERY worried about supplied voltages and of course back-feeding power. I used a USB multimeter to determine that there is ZERO power being back-fed to the computer's USB port when not in use. This is unfortunately a VERY common problem with some of the cheaper USB switchers/KVM. I tested power at the devices AND the lines going to each client and everything was flawless. HOWEVER I would HIGHLY recommend purchasing an external power supply!! I did notice that if it was bus powered that the 5v USB line would drop down a little too low for my taste and below USB spec. Probably wouldn't "harm" anything but one might experience wonky behavior from their devices, especially things like bright RGB keyboards, external hard drives, bus-powered audio equipment etc. I purchased this power brick unit - https://a.co/d/ienOG3u which I highly recommend! I also through a multimeter on the power supply and it passed with having very clean voltage. The power brick linked above is perfectly in spec with what the manufacturer suggests (5V 2A). With the external power supply connected the 5V line at the devices were now within USB spec (+/- .25v). With a full on RGB keyboard the 5V line was close to being on the money and was pulling about 400mA, right where it should be for USB 2.0 devices. NOTE: that the unit does NOT come with a micro USB cable OR power brick! MOUNTING & INCLUDED CABLES: I have a very large, deep desk and each machine is on separate sides of my 48" display. Another pet peeve of mine is cable management. I don't like having any cables visible on top of my desk or on the floor, with the exception of an artisan coiled keyboard cable ;). That being said running the USB cables included wouldn't reach with having the unit mounted under my desk. I mounted it with some 3M mounting tape (not included) but do note there is no mounting points on the unit so you're on your own there. I placed the unit on the right hand under side of my desk and can easily find the button due to the "ring" design of the button, it's very easy to find while not looking at. The only downside is that you can't see the status lights. I purchased some longer quality USB 3.0 cables and it was a non-issue on both PC and Mac! SWEET! To the PC I ran a 10' cable and to the Mac I used a 6'6" cable - remember the power brick is VERY important at this distance!! The unit comes with 2 x 1.5m cables (4.92 feet). Cons: - USB Devices will "Sleep" with the computers off but RGB keyboards etc will still be lit up if using the external power. This is highly dependent on the device and YMMV. - Once either client (PC/Mac) goes to sleep you can no longer wake them by jiggling the mouse/hitting keys on the keyboard IF it was switched to the alternate computer when it fell asleep. This is by design on both PC and Mac as a safety/security feature. It's no big deal though, you can just hit the power button to wake either type of machine and the USB devices come back alive again even at the login screen. - Switching is very fast when comparing to other units but switching is not perfectly instantaneous. It is usually about ~2 seconds. - Glossy Black Plastic = Finger Print Magnet! - Didn't include a power brick/cable That's it! Hope you enjoyed the review! I do want to mention that I have only tested this with mouse and keyboard... I have no need for external storage or swapping audio devices or other high powered USB devices... BUT I do highly recommend this unit and I ALWAYS update my reviews if stuff goes sideways. So far I'm very impressed and extremely happy I didn't have to go down a rabbit hole of dozens of KVM/USB Peripheral Switchers. BUY IT (and the power brick/cable)!

I really wanted to like this thing. I have two computers at work and wanted to be able to share a keyboard, mouse, headphones, and flash drive between the two. This device perfectly fit the bill and I excitedly ordered it. I really thought I would be soon showing off my new toy to the other office drones, proud of my mastery over desk space utility and efficiency. Today, I have finally completely given up on it and will be tossing it in the trash (aka, selling it on craigslist lol) The problem started with my mouse, a brand new Logitech G603. At first I thought there was an issue with the mouse because it would work perfectly, but then, without warning or reason, I would get ridiculous mouse lag. I am talking over a second between mouse movement and cursor movement. Removing and reinstalling the usb receiver would alleviate the issue temporarily, but it would always come back. I did a bunch of research into the problem and found that usb switches can be the problem. I plugged it directly into my tower and sure enough... no more issues. Onto the headphones. I use a bluetooth receiver to connect to my Beats Studio Wireless. I've had these headphones for about five years now and they have been absolutely rock solid, they connect to everything and never lose connection. I've loved and used them so much I recently replaced the ear cups because they were falling apart! Now, with plugging the BT USB receiver into this switch I would intermittently experience a background static. Again, reinstalling the receiver would temporarily alleviate the issue but it always comes back. Furthermore, it has started dropping the connection. At first I was worried my trusty beats were finally failing me. A distressing thought with replacements commanding a hefty price tag. But again, I've plugged the receiver directly into the tower and now experience clear audio with no drop outs. Now, to be fair (but not so fair I give a star back, lol), my keyboard, a Logitech G613 and my thumb drive, a sandisk whatever micro thingy, have had no issues. Also, it switches back and forth just fine. Maybe you think that deserves an extra star. Maybe there are inherent issues with USB switches that are technically impossible to overcome to work with the high bandwidth devices I am trying to use them with. Maybe... maybe. But I don't care. If all my devices don't switch from computer to computer, it's useless to me and therefore one star. Sorry not sorry. Ignore my review if you have a different use case or (gag) a low bandwidth mouse.

10/15/2020 Update. I'm not afraid to admit a mistake on my part, it turns out my desktop was playing up due to the infamous Windows 10 mouse lag issues and so I tried out different and older usb hubs to investigate the problem. The problems resulted in me 'Refreshing' my system in Windows 10. The problems persisted and one by one I updated the drivers of my system, making sure I covered everything. I still have the mouse lag issue, but it look like it has gone away, by setting it to have mouse trail turned on and set on a minimum trail. My pointer now, no longer sticks and I don't seem to have that visual slow down on my system. Now back to the Ugreen USB Switch: I have plugged in the micro usb power at the back, just in case, and as advised! I now switch between my laptop and desktop as intended, I cannot ask for more at this time. I have my keyboard, mouse, tablet and webcam all hooked up and works as intended on each, with no hiccups at this time. Original review: The switch has erratic behavior, mouse pointer jumps and lags, the keyboard would also continuously type or execute commands last commands, like space or enter, making me hit the escape button a lot to cancel. I switch between my work laptop and my desktop, both with Win 10. I have also unplugged the one of the other and this the problems persist. Unfortunately there is no software or drivers to help eradicate the problem the usb switch brings with it!
