USB Switch 4 in 4 Out, USB Switcher Selector 4 Port for 4 Computer Share 4 Devices Keyboard Mouse Printer Scanner with Desktop Controller and Cables

I am starting to work with some small/mini computers on a small desk where space is limited. Sharing keyboards, mice etc works well with the USB Switch.

Works perfect,Heads up that I didn't need to plugin the power cable (A laptop will power the switch on its own)I bought another Switch previously that got wrecked because the USB receptacles allow you to put it in backwards short circuiting the switch (Watch out for any Blue tabbed receptacles)

So I have a few systems and I need to swap my keyboard and mouse around. Well, I plugged in everything and CRAP. Doesn't work. I'm thinking yet another AMZ return. Just for grins I connect it inversely. In is Out and Out is IN. And OF Course it worked. WTF. OK works as designed except connect your PC to the USB in and your devices to the USB Out.

The media could not be loaded.  I bought this thing because I had been using multiple Bluetooth keyboards and mice for years and while that works okay it can be a little slow and most only can handle 3 computers.This thing is EXTREMELY fast. You just plug all your computers in via usbs which are included in the box and bam you can use one keyboard and mouse for all 4 and switch between them just by pressing a little button which is SO much faster than Bluetooth. I am a QA tester so need be able to test all day on all devices quickly and this thing does that with no problems. It’s a nice cheap working solution. I posted a quick video above of me using it and while I am slow switching between PCs in the video it’s just because I am holding my phone filming working with it is almost instantaneous switching between all 4 devices. Hopefully this helps :)

Bought this to share keyboard, mouse, and a portable DisplayLink monitor that takes signal and power through a single USB-A cable. Could not get the monitor running despite feeding extra power through the Type-C port provided for this purpose. Even worse I couldn’t get even a keyboard to work. Returned.Asked for and received a replacement which was visibly a used item (loose cables, no packing inserts see pics, you can guess which is which).No matter, the replacement fared no better and was returned as well. I still can’t understand how used items get back into inventory without so much as a cursory inspection of contents. Very disappointed.

I needed a usb switcher hub to be able to switch among 4 difference pc's with one keyboard & mouse. It's great & so far it's been perfect. In 2023 most usb switching hubs come with usb 3.x but I've read a few different usb 3 hubs that warn about some of them having issues with wireless keyboard & mice. So I specifically searched for a usb2 compatible switching hub. Here's the catch, if you're trying to share a usb 3.x flash drive amongst multiple pc's it will still work with this switcher but you won't get the usb 3 speeds that are possible with a usb 3 drive. I don't plan on doing that so I made the priority to be compatible with a wireless mouse & keyboard. If you're in the same predicament that I was in don't wait to purchase because there aren't many usb 2 specific switching hubs left to purchase.

Edit: (1/17/2024) Less than a year later...it died. Basically it stopped continuously connecting to any of the computers, two of which went through hubs, one directly. It's basically a power issue, because my keyboard has a power light that flickers on and off in weird patterns. I tried a new power cable, and a new charging brick (5v/1a) and nothing changed, so it's the power handling in the switcher.TLDR: This works with 3 computers - 1 Macbook Pro, 1 Mac Mini, 1 Dual Boot Ubuntu & Windows. The "key" (remote dongle to change between computers) is nice.Overall it's great.I was gifted (recycled) a rather nice Mac Mini.I wanted to use the same keyboard and mouse as I've done with a Macbook Pro and a dual boot Winows/Ubuntu.My old usb switcher (Ugreen 2.0, and it's good) could only handle 2 computers.So, I got this.Basically I've read way too much about usb 3 switchers and hubs not playing nice with 2.0 peripherals so stuck with 2.0.I now have a mouse, keyboard, usb audio interface, and a webcam connected to all 3 machines and everything works.What's really nice is the "key" which is basically an extension of the switcher on the box which can be extended to a desktop.Also of note, which isn't mentioned in the description, this does come with a usb A to C cable for charging, but no charging brick.I just use an old phone charger (5v 2A).This is inexpensive and works exactly the way it should.

Works great. Just like it's supposed to

Works perfectly. Allows me to use same keyboard, mouse and USB mic across 2 PC's and a Mac.

aumento mi productividad, es muy facilde usar

This is a decent little switcher which gets the job done, however potential buyers should be aware that it doesn't include a feature only available in more expensive models and brands..."EDID" (Extended Display Identification Data) allows a switcher box to spoof the computers it is attached to so that neither system thinks the screens are ever disconnected. That means, from the perspective of the Operating System, even when you're switched away from one machine, it still thinks the screens are connected and receiving a signal.This switcher doesn't do that.This means, every time you switch back and forth, the computers think, "Oh hey! A new monitor just got plugged in! Let's see now.., do I have a driver for that...?" Much mucking around ensues.Now, with a modern OS and if you're only sharing a single screen, this can be a minor issue. But if you happen to have multiple monitors in play, (and if, like me, one of them happens to be a Wacom LCD drawing board), then you can expect all sorts of annoying shenanigans to occur, with the minimum hassle being that your personalized window layouts default to factory settings. That can be very annoying if you need to swap between work stations multiple times during the day.If, however, you do not need to switch between active computers on the fly and if your monitor setup is relatively simple, then this little switcher is a great way to share a mouse, keyboard and screen between two systems.

Have only had this product for 2 weeks, and it works are described. I tried it on 3 different computers and with 4 different peripherals.Mouse, Keyboard, Camera all work, despite what others said about software/gaming mice not working. There might be an ever-so slight delay in mouse response introduced, but it is in the hundredth of a second, only potentially impacting gamers, not noticeable by anyone else.The buttons on the remote are a bit loose, so they make a sounds when shaken, but not a big deal and everything works well. The ports are not too tight, not too loose and the switch button is electronic, not analog.Most people in need of a KVM think they need a video port. In this case, I was able to hook up multiple video inputs in my monitors, and they swap automatically to whichever computer is on and provides signal, and if multiple are on at the same time, then can switch on the monitor individually, so the video inputs on this device were not necessary for me.It did what I needed it to do, which is unclutter my desk of 3 keyboards and 3 mice, so if that's what you need, then I recommend to buy it.

It's very reliable. No glitches experienced connected to USB external DAC at 192 khz, Keyboard, printer, mouse. Perfect resource switching between Windows 11 and Mac OS (Sonoma).
