UCEC PS/2 to USB Adapter Converter for PS2 Keyboard Mouse Accessories

I have an old mechanical keyboard that I refuse to give up. The problem is that it speaks PS/2, and my current machine speaks only USB. Enter this cable, which turns a polite but firm incompatibility into a non-issue. The converter handles both the keyboard and mouse PS/2 ports simultaneously via a single USB connection on the host side. The color coding on the PS/2 ends follows the standard convention (purple for keyboard, green for mouse), so there is no guessing. It is an active conversion with a built-in IC chip, which matters because passive adapters frequently fail with keyboards that require actual PS/2 signaling rather than a simple passive wiring remap. Plug it in, and it just works. No driver installation, no configuration, no reboot ritual. Compatible with Windows, Linux, and also plays nicely with the PS/2 ports on KVM switches, which is a less common use case but a genuinely useful one. The only quirk worth mentioning is that occasionally and very rarely a keypress may seem to hang, but in practice this is uncommon enough that it has never been a real issue. If you are trying to breathe new life into a beloved old peripheral or need PS/2 support for a KVM setup, this cable delivers exactly what it promises at a price that is basically a rounding error.

I have a 1980s-era IMB mechanical key keyboard with a PS/2 plug. This little adapter seems to be working fine, without any missed keypresses or unwanted keypress repeats. Two remarks, though: 1) The USB plug is fatter than I'm used to seeing, and so may not fit next to other (normal width, perfectly flat) USB plugs. You will have to find an unused USB port with nothing next to it. If you don't have one, then order a short generic USB extension cable at the same time you order this adapter and you'll be able to plug it into any available USB port. 2) The PS/2 sockets are a very tight fit. Be patient, look closely, align the cable's keytab with the socket's keytab hole EXACTLY, and push hard. The plug will suddenly snap into the socket. It's a good, secure mate. 5 stars, highly recommended as long as you prepare for the above two oddities.

USB to PS/2 Keyboard / Mouse splitters are definitely NOT all created equal. Most are merely plug adapters and not true converters. And of course the vast majority are all simply generically-branded so they are hard to research and have virtually no driver support. This becomes even more of a challenge if you are wanting to use this on a macOS. After quite a bit of research I concluded that this particular unit would indeed work on a Mac. Since there are few brand names I mostly had to go by the picture, and the long (2-inch) thick part on the USB end was indicative of this being an actual converter which is what I needed to get my IBM Model M working on my Macbook. Sometimes it does glitch out and I have to tap the ALT key (mapped to the mac command-key) a few times, but this is pretty rare. TIP: For my 20+ year old Model M keyboard I remapped ALT to command, CTRL to option, and CAPS LOCK to control (very rarely used by anything on the mac), as well as PAUSE and SCROLL LOCK to be brightness down and up. This was much cheaper than buying a modern Mac-compatible Model M-style clicky keyboard from Unicomp ($120+) and I would definitely recommend this adapter over all other generic-branded ones. For PC/Windows users, you could definitely get away with a cheaper-made adapter, but for the price I would get this real converter and know that you have something that will be useful on a variety of computers. I had a couple non-brand and a logitech USB-PS2 adapter, and none of them worked at all for macOS. Even if you don't care about Mac, I've had plenty of USB-PS2 adapters over the years, and sometimes they don't even work on particular makes/models of PCs!!!, so getting a REAL converter like this is just smart.

I'll start with the important part: this is an active converter as advertised, and it's worked for every keyboard I've thrown at it - IBM Model M's, Focus FK-2001 and FK-2000 Plus, countless old dome with slider keyboards, everything. It isn't perfect. Once in a while (very rarely), a key seems to get stuck. This is rare enough and the keyboards I've been using this for are old enough that I honestly can't blame this converter any more than I can blame the membrane/PCB or controller on the keyboard. It's a very minor annoyance that I honestly didn't run into enough to make me mad. Now, something you need to know before ordering this: you might not get a product with packaging branded UCEC. When I first received my order, the one I received didn't work (my computer wouldn't recognize it and it heated up quite hot), and when I looked at the packaging, it was labeled J-SEK rather than UCEC. I ended up contacting the seller, who told me that it was indeed the UCEC product, just rebranded to J-SEK. Now, I honestly wasn't completely convinced by this, but they sent me a replacement (with the exact same J-SEK packaging) that I've been using for 3 months. Is it possible that it isn't really the same product as the UCEC converter advertised? Yes, but this is such a generic product that even if that's the case, this product is still a decent PS/2 to USB active converter that does the job, and that's what matters.

This adapter allowed me to use my old keyboard and mouse with my new computer. Works well and only one USB port needed for both devices.

It just works, plug in PS2 keyboard and mouse they start work immediately

I give this good product * for sheerness -There is no sheerness to it at all. I give this good product * for thickness. There is way too much thickness in this product. I give this product overall rating of ***** because this is a very good product. I have an old Kinesis keyboard. It was given to me by one of the best bosses I had in this computer industry. I have typed hundreds of thousands of lines of code on this keyboard. I disassembled it, soaked the key caps, washed every part of it so many times over the years. The Esc. key is a bit lazy, the 'C' needs some polishing and lubrication, the contacts in the Back-Space key switch got all mangled and then reshaped. It uses the old, original PC connector, a large DIN 5 pins connector. Over the years, I added a PC to PS2 adapter. When I decided, at the age of 70, to write some code again, out came the Kinessis, all dusty and dirty. One more restoration, and off we go. But for that to work, I needed a USB adapter. I tried few others with no results at all. But his one worked! I am typing with it connected to a new all Amazon computer build, and you can see I am in no shortage of words. If you have an old keyboard around, get two of this adapter; One to use, and one to use when/if someone manages to destroy the one you are using. Go for it - it is inexpensive, and it works very well.

I bought this to use with an old (but high quality) KVM switch that has no USB ports, only PS/2. I have a new computer with no PS/2 ports, only USB. So I needed something to connect the KVM's PS/2 output to the new computer's USB input. This isn't it. It handles keyboard input just fine, but goes crazy with the mouse. The product description says that it works with KMV switches, but it doesn't work with mine. For people with a setup similar to men, I've tried 4 different converters and the only thing I've found that works is the Perixx PERIPRO-401.

excelente buena calidad !!

Rien a redire, fonctionne très bien

Ich habe von meiner Firma jede Menge PS/2 Tastaturen und Mäuse geschenkt bekommen. Mit Hilfe dieses Adapters kann ich sie an modernen Geräten benutzen. Getestet an 64bit und 32bit Systemen, funktioniert tadellos.

Funciona muy bien, habia comprado otro adaptador y no funciono en mi PC con Windows 11, este adapador reconocio mi teclado PS/2 sin ningun problema y sin instalar ningun software, aparte de tener buena calidad. Recomiendo el producto.

During some changes I wanted to have direct access to my server which had only USB sockets, but my spare key boards and mice were PS2 only. This item was a perfect way to overcome the miss match, thank you. I can now run the server headless or via direct access and the combo works perfectly.
