I heard that the Security team at the new company I'll be joining in a couple weeks forbids connecting unapproved USB keyboards/mice to employee workstations. However, if you use PS/2, you can connect any keyboard and mouse you like. So it seems like users of unapproved USB keyboards could work around this policy by using a USB->PS/2 adapter.

Since the KeyMouse combines keyboard and mouse signal into a single USB connection, I'm guessing that using a single USB->PS/2 adapter with the KeyMouse will not work, and instead I need something I can plug the KeyMouse USB cable into that splits the signal into one PS/2 keyboard cable and a second PS/2 mouse cable?

Can someone on the KeyMouse team please advise what kind of adapter(s) KeyMouse users in this situation need to use?

I tried searching online (including in these forums) before posting here, but it wasn't clear from the results what I should get (see e.g. https://google.com/search?q=split+usb+into+ps/2+keyboard+and+mouse) so I figured I better ask the experts. :)

Thanks!

It seems very unlikely that this is possible, but you could try this: https://smile.amazon.com/Minicom-Converter-Switch-Extender-0DT60002/dp/B00404YD8W/

Some KVM switches support USB mice and keyboards explicitly (and emulate them), so you should ask the security group if they have a USB KVM that they support (since it would mean that you're not plugging a generic USB device directly into the computer).

Other than that, you're probably out of luck.

Thanks, Cameron, much appreciate your suggestion. I zoomed in on the photo of that product and it looks like the PS/2 ports are female, which also matches the diagram linked to in the description, which suggests this isn’t quite the same thing as what I need : https://images-na.ssl-images-amazon.com/images/G/01/electronics/detail-page/B00404YD8W-0DT60002-connection-LG.jpg (let me know if I misunderstood)

If nothing readymade exists, shouldn’t it be possible to DIY this with the KeyMouse and a couple PS/2 cables hooked up to a Raspberry Pi running a small program that forwards keyboard and mouse events from the KeyMouse over the PS/2 cables? If so, would gratefully pay anyone who could make this for me! Though hopefully it’s just a matter of finding the right combo of existing products…
