\$\begingroup\$ I am quite aware you can get ready made off the shelf adaptors to connect old ps/2 keyboards to USB. But I am curious as how would one do it themselves? I have tried just rewiring an old keyboard to a USB cable as they both have 5V and ground and 2 data connections. Though USB has a differential DATA +- and ps/2 has a data and clock wire. So after trying a basic rewiring it didn't work so there has to be some conversion going on but what? The puzzling thing is going from USB to PS/2 works but going the other way doesn't work. Why? Edit Ok so in some more research, I think I understand the why now. As USB devices need to be registered and be able to give data to the OS about what it is when requested by the OS. ie. report back a VID and HID code. Although all the 'scan codes' that the keyboard sends to the system should still work with modern systems. As this was based on the original IBM PS/2 AT keyboards and this protocol has been carried though to today. Edit 2 More info found on the electrical interface needed here. It seems its a not that easy but doable task to create your interface with the use of a cheap microcontroller. The connection between the microcontroller and the ps/2 keyboard seems straight forward enough but then from the microcontroller to USB is another story... Edit 3 After a bit more searching I discovered that Microchip released a Technical Brief with quite a complete guide on how to do exactly what I was after! Its TB055 and includes the source code for PIC uC. asked Dec 2, 2016 at 1045 crowiecrowie5221 gold badge3 silver badges10 bronze badges \$\endgroup\$ 4 \$\begingroup\$ The converters like these are just for the connections. It will not make a USB-only keyboard work in PS/2. It will not make a PS/2-only keyboard work on USB. The keyboard that came with such an adapter was capable of both USB and PS/2 connections. It detects if it is plugged into a USB port or a PS/2 port and then adapts to that connection type. answered Dec 2, 2016 at 1053 gold badges93 silver badges183 bronze badges \$\endgroup\$ 4

I have seen a few videos on Youtube about converting a PS2 into fo USB with the 4 primary wires soldered to the controller board. My question I've heard a lot of these fail because the OS will search for a non existing driver and fail to work. Have any of you had success with this option and could you post a link to the details? I have not problem rebooting to make these old ones ps2 work with the modern os's but would like to make it plug and play.I've tried those little adapters ps2 male into female Usb adapter they don't provide power to the board I have plenty of the new cheap usb's but I really like using these old ones. Thanks..;. Last edited Apr 25, 2022 Mar 16, 2013 164,217 14,616 184,590 3 Thanks USAFRet, for the quick reply.

Maybe not this exact one, but similar. 5 I've used several of these with old keyboards, no problem. Maybe not this exact one, but similar. Yes, these work with a USB keyboard in to the USB to PS2 adapter, not what I'm looking to do.? Mar 16, 2013 164,217 14,616 184,590 6 Ah, sorry...I was reading this the other way around.

You need this adapter or, this one gives you BOTH PS/2 sockets for keyboard AND mouse These certailnly should work - the electrical lines on a USB2 port are the SAME as 4 of the pins of a PS/2. So if the old keyboard did work on a standard PS/2 socket, it should work on USB2. UNLESS, of course, the keyboards were used on mobos that had NON-standard PS/2 sockets or electrical power supply lines. Drivers - well, there could be an issue. IF the keyboards was a "standard" one, the generic Windows keyboard driver should suffice. BUT if it had special features that required its own driver, the old driver is VERY unlikely to work in current Windows, and might not even bother to look for the keyboard on a USB2 port. 9 So you have a keyboard with a PS/2 5-pin DIN connector on its cable, and you want to plug it into a standard USB2 Type A socket.

Thanks Paperdoc, I'll check them out online and maybe try one. I'd still like to find out who's done a mod with a usb cable and replaced the ps2 cable and if it worked? But I think this will suffice.

The short version of this answer boils down to something pretty simple and easy Cheap, easy try more different keyboards with your passive PS/2↔USB pin adapter OR Not cheap, still easy buy a really expensive, nice keyboard that also works over PS/2 and take it as an excuse to get yourself a nice keyboard for day-to-day computing! The passive PS/2↔USB pin adapters not working may be merely a factor of your choice of USB keyboard to be converted being too new. If you have that many more USB keyboards stashed away, it might be worth trying the adapter on several different keyboards based on a few key factors. I'll try and communicate what I've noticed about this stuff as best I can. These aren't hard and fast rules for finding a PS/2 adaptable keyboard, as much as a short gist of guidelines that can hopefully point you at a compatible keyboard in your spare parts pile. In the below image, take notice of the styling of both the meta/"Windows" key - a flat modern icon of Microsoft's recent motifs, and the OEM Dell branding - indicating this keyboard likely came bundled as part of desktop system. Both of these points would suggest this keyboard is probably too new to utilize a multi-mode controller IC. Lacking a multi-mode controller IC, this keyboard would be incapable of detecting when it was plugged in to a PS/2 port with a passive pin adapter and would lack the internal logic circuitry to enable to function as anything but a USB keyboard. It also features an thematically darkened aesthetic common to a newer era of consumer computer hardware - probably the loudest indicator of a keyboard's age outside of chiclet keycaps. Supposing you have enough old USB keyboards around, finding one that's closer to the era of when PS/2 devices were still popular may allow the use of one of these passive adapters. In the image below, it can be seen that this keyboard features an older styling overall. The icon on the "Windows key" hails from the increasingly distant era of Microsoft's Windows Vista design motifs - an OS at it's prime in a time when PS/2 hardware was still in style. The OEM Logitech indicates this keyboard is more generic than the Dell or HP, Acer, etc..., and was probably purchased discretely for use with any given desktop system of the time. This keyboard also features a thematically lighter aesthetic that comes from a remarkably obsolete era of computing. These points don't add up to guarantee a cross compatible keyboard, but are positive indicators in that direction. This is a keyboard more likely to have a multi-mode controller IC which would function with the typical passive PS/2↔USB pin adapter. The second linked image could easily be a better example, but still illustrates the point. If you absolutely need a different but specifically PS/2 keyboard at the end of the day, good 'ol ebay tends to be an acceptable place to check. In between all the random and poorly priced stuff one can sometimes find some good deals. Please note, the above link is not in any way an endorsement of the listing or seller and indeed I expect it to be well expired by the time this question is in google results for anything, but a mere example of the point. It may also bear worth reframing of the problem as an opportunity to buy a nice buckling spring Model M keyboard - they came in PS/2 natively back in the day, and are within the ballpark of $100-200AUD depending on various factors. If my understanding serves me, unicomp and cherry may also have some PS/2 compatible keyboards available which are generally well regarded. I would also not be surprised to learn of any modern "gaming" oriented keyboards on the market that have snuck a PS/2-compatible mode into their controller IC for use with the passive adapters, but that's far more web research than fits the scope of this answer.

A USB to PS/2 converter is not a straight-forward wiring pin-out adapter between the 2 different connectors. The converter contains a small chip that talks PS/2 either the keyboard or the mouse version to 1 connector and that acts as a USB device which involves being able to correctly respond to various USB commands to the other connector. This USB device must among other things identify itself to the computer as either a "USB HID mouse" of a "USB HID keyboard" as appropriate. There are converters that have 2 PS/2 connectors so you can connect both a mouse and a keyboard to 1 USB port. Internally such converters identify themselves to the computer as USB device with 2 sub-devices the USB standard allows for this. Allegedly there also exist "smart" converters that can work with either a mouse or a keyboard and will auto-detect what is attached. I have never seen one myself so I can't tell you how well that works.Berikutini cara memeriksa apakah keyboard anda masih berfungsi dengan baik atau tidak.
