My Optiplex 980 with Windows 7 Pro64 won't recognize my PS/2 keyboard and mouse. It'll recognize them on SUB, but I want to keep those ports free since I do have the PS2 slots (USB devices with PS2 adapters). They are the same exact keyboard and mouse used in several other computers with XP.

As far as I know, Windows 7 and newer no longer recognize the legacy PS/2 ports.

I don't think so. This would be new crazy news to me...and I work in a computer shop.

When you turn on your computer, go into the BIOS and double check that the legacy PS/2 ports are enabled. It's a Dell thing, the ports are probably not turned on for Mouse/Keyboard. Not sure where to direct you for what menu to look in, but I'd be willing to put a small sum of actual money that the ports are just turned off by default. On a lot of motherboards with the combo Mouse/Keyboard PS/2 port, you have to manually set which one you want it to work with. Also, make sure you're not plugging them into the wrong port. Keyboard is blue, mouse is green, when the ports are stacked one on top of the other, keyboard is always on the bottom, closest to the PCB, the mouse is always on top.

Why not just get a USB hub? I feel like this is being made way more complicated than it should be.

why the desire to conserve USB ports? did they suddenly stop selling USB hubs?

I've heard of PS/2 on 8 though, which is after 7 :/

No.

The USB devices work in USB ports. jsut fine.

But when using a PS/2 adapter to plug them into PS/2 slots, that doesn't work.

I got some more info for you. Some Windows 7 security updates were oriented towards limiting or preventing remote access, but they locked down the PS/2 drivers.

You would have to remove the following security updates: kb2913431, kb915597, kb979309, kb2621440, 2529703

You will also need to remove the corresponding registry changes that match those security updates. The registry changes needed to be removed from these updates are:

C:\Windows\Microsoft.NET\Framework\v1.0.3705\system.enterpriseservices.dll

C:\Windows\Microsoft.NET\Framework\v1.0.3705\system.configuration.install.dll

C:\Windows\Microsoft.NET\Framework\v1.0.3705\wminet_utils.dll

C:\Windows\Microsoft.NET\Framework\v1.0.3705\microsoft.vsa.vb.codedomprocessor.dll

C:\Windows\Microsoft.NET\Framework\v1.0.3705\mscordbi.dll

C:\Windows\Microsoft.NET\Framework\v1.0.3705\mscorrc.dll

C:\Windows\Microsoft.NET\Framework\v1.0.3705\diasymreader.dll

C:\Windows\Microsoft.NET\Framework\v1.0.3705\vsavb7rt.dll

C:\Windows\Microsoft.NET\Framework\v1.0.3705\microsoft.jscript.dll

C:\Windows\Microsoft.NET\Framework\v1.0.3705\mscorsec.dll

C:\Windows\Microsoft.NET\Framework\v1.0.3705\iehost.dll

C:\Windows\Microsoft.NET\Framework\v1.0.3705\system.data.dll

It's part of Windows 7 security updates, but it is true. The updates were supposed to help limit unauthorized remote access, but they locked down the PS/2 drivers. Here: http://www.tomshardware.com/forum/71345-63…

It's not really a universal, because there are a large number of computers that don't have .NET installed on them. I have a very large number of clients where unless I install .NET, it's never been on their computer before.

But even as listed, if you've been using PS/2, it continues to work, it's not an issue unless you decide to switch between USB and PS/2. Still a bit of a moot point if the OP doesn't have .NET installed.

I thought .NET tagged along as part of the standard security updates.

It does sound like OP has switched between USB and PS/2.

.NET is often bundled with many programs today, so when it's present on a system, yes, you'll get all the updates for it automatically. It's not like Silverlight that tries to install itself through Windows Update when you don't have it though.
