PS2 keyboard and mouse not functioning on Windows 8.1

My new Asus I7, 16GB RAM computer was delivered with Windows 8. I immediately upgraded to 8.1. Unit came with a usb keyboard that I don't like. So I plugged in several of my PS2 keyboards and mice. Nothing happened and they didn't work before or after rebooting. Went to Device Manager-Keyboards with the ps2 plugged in. It showed only USB keyboard NO PS2 in list.  Various forums speculate that PS2 is no longer supported by Microsoft. Other people show their Device Manager and PS2 is in their list on Windows 8.1.    The PS2 port is on the same internal board that also has 2 USB ports. The USB ports work.    Two questions: 1) does microsoft W8.1 support ps2 devices?    2)    If yes it is supported , what is going on with my PS2 port and its apparent lack of a driver?

Hi,


You might be facing this issue due to incompatible, outdated or corrupted device drivers. Yes, PS2 device should work on Windows operating system.


Unplug all USB devices (while the system is off) plug in your PS/2 mouse and keyboard while restarting the computer. That should resolve the issue.

Follow the methods:

Method 1:

The hardware and devices troubleshooter can detect and fix errors and incorrect settings in devices. You can refer these steps to run this troubleshooter:

  • Press Windows key +X, select Control panel.
  • Change the view by option on the top right to Large icons.
  • Click on troubleshooting and click on the view all option on the left panel
  • Run the Hardware and devices troubleshooter.

Method 2:

Check in the Device Manager for the hidden device entry. Once you find the device, uninstall the device by following this step:

  • Press Windows+X keys and select Device Manager. Note: If you are unable to find any device with any marks then check by enabling hidden devices.   
  • Right Click on all the USB devices and select Uninstall.
  • Restart the computer and check if it reinstalls the driver for the USB PS2 devices.                

If the issue still persists, proceed to the next method.


Method 3: If you have Intel XHCI feature on BIOS try disabling it and check. For further assistance you may contact the computer manufacturer.

Important: Modifying BIOS (Basic input output system)/complementary metal oxide semiconductor (CMOS) settings incorrectly can cause serious problems that may prevent your computer from booting properly. Microsoft cannot guarantee that any problems resulting from the configuring of BIOS/CMOS settings can be solved. Modifications of the settings are at your own risk.


Refer to the link to update drivers on Windows 8.1:

Thanks Pinaki, yours is one of the most complete, intelligent, and thorough replies I've ever read let alone been assisted by.


I'm still working through your suggestions. The results so far:

*  all drivers were and are up to date,

*  hidden drivers did not include PS2, under keyboards in device mgr, one extra HID - usb keyboard was listed for a total of two (one was hidden).


On to the next step. Disable all usb's.


As the guy who jumped off a cliff said "so far so good"

Hey there, Pinaki. I was having the same issue on my desktop running windows 8.1, my hardware may be different from NotJunkDamits but unplugging all of my other USB devices and restarting with only the PS/2 keyboard plugged in resolved the problem.
