Brief diagnosis and practical next steps.

The symptoms in ’s post (no onboard PS/2, using an adapter, keyboard mostly OK but the mouse only works after being re-plugged, and in-game only one key registering) point to two separate, common causes: (A) the adapter being a passive plug-changer so the mouse isn’t being properly enumerated at boot, and (B) keyboard matrix/USB-rollover limits that make simultaneous key presses fail. and were on the right track; below are concrete tests and fixes that were not covered yet.

  1. Quick isolation tests
  • Try a known native USB mouse/keyboard in the same ports. If the native USB devices work at boot, the adapter is the culprit.
  • Plug the adapter/device directly into a rear motherboard USB port (no hubs or front-panel extensions) and cold-boot. If it still needs re-plugging, watch Device Manager in Vista for “Unknown USB” or multiple HID entries and remove old/unrecognized items before rebooting.
  • Try the keyboard outside the game (Notepad) holding several keys to see how many register. If simultaneous keys are lost there too, it’s a hardware/protocol limit, not the game.
  1. What the problems usually mean and how to fix them
  • Passive PS/2->USB adapters require the peripheral itself to support USB signalling; many mice don’t, so they won’t enumerate reliably. Active protocol converters exist but are rare and often cost more than replacing the mouse.
  • USB “boot”/HID limits and cheap keyboard matrices can restrict simultaneous key presses (USB boot reports are limited to a small number of simultaneous keys). For reliable multi-key gaming, a native USB gaming keyboard with NKRO/anti-ghosting is the simplest solution.
  1. Practical recommendations
  • Easiest, most reliable fix: buy a proper USB mouse (and, if you need multi-key gaming, a USB keyboard advertised with NKRO/anti-ghosting).
  • If keeping PS/2 gear is important, look for a genuine active PS/2→USB converter or test the old devices on a true PS/2-capable machine first. Before changing drivers or BIOS settings (as suggested), make a restore point and install the latest chipset/USB drivers from the board vendor/Intel.

Credit to and for the original troubleshooting direction; the above gives step-by-step tests and pragmatic choices so the thread’s results aren’t left ambiguous years later.

I found this, which sounds like your issue:

The vast majority of commonly available ps2 to USB converters are simple passive ADAPTERS that simply change the plug shape to match the outlet. These ADAPTERS only function to connect the ps/2 wires to the approximate USB wires. Simple ps/2 to USB adapters do not use specific software drivers.

In general, most users having trouble connecting their keyboard to newer computers are looking for a ps/2 to USB signal CONVERTER. These devices use an integrated circuit (pre-programmed chip) to actively translate the ps/2 keyboard signal and convert it into a USB keyboard signal.

This allows the vintage ps/2 keyboard to be automatically recognized by the operating system as if it were a standard, modern USB keyboard. A well-designed active ps/2 to USB converter will use the built-in operating system drivers for a USB keyboard

However I can't find any of these 'signal converters' they talk about, only the adapters. Well I've got you started anyway.

Member Avatar for jbennet

did you look in the BIOS like i said?

Secondly, what OS are you using
Thirdly, have you got the necessarry chipset drivers installed?

Member Avatar for firekid1239

Why not just buy a USB KB and Mouse? They are relatively inexpensive and would solve your problem.

Count on me to point out the obvious...lol.

Member Avatar for Suspishio

He changed his mind. In post #3 he said he'd buy a new KB/Mouse.

Member Avatar for jbennet

well obviosuly not because in 6 he says "Keyboard wORKS fINE
But Still Mouse Ps/2 to Usb Doesnt Wokrs"

Member Avatar for Suspishio

Well obviously 'cos this thread's still running and he changed his mind from post #3 like I said.

Anyway find me a a USB that "Wokrs" and I'll find you a "mus" (post #1) to fit it!

Of course I have toggle USB Legacy - Enable but no Response

Okay Guys Settle down
I will Buy a Mouse

Anyways thanks 4 ur Help..........
