PS2 keyboard not recognised by a new Win 11 Pro machine

Hello

I recently bought a new pc and installed Win 11 Pro.

Ver. 22H2, Build 22621.755,with experience pack 1000.22636.1000.0

I would like to connect a PS2 keyboard, but it is not recognised by the new hardware. The keyboard works fine on the previous PC which is Win 10.

In device manager, there is no PS2 driver shown. There are three HID KB devices shown.

I have chaged the Dword value in ..

HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services \i8042prt \ start

to 1 but the keyboard is still not recognised.

Any suggestions to solve this problem?

TIA

Dave Johnson

    Morning all

    I posted a question (Oct 28th 2022) and have found a solution. ( It worked for me) That thread is now locked so I've posted this FYI .

    I had a look at the existing drivers. All the files in the cab were there with later dates so I didn't change them. I had another look on the web and found this ...

    https://www.google.com/search?client=firefox-b-d&q=ps2+keyboard+not+showing+in+device+manager#fpstate=ive&vld=cid:77aca642,vid:rJzGaBozgi0

    The problem he described didn't exactly match mine but I followed the procedure he suggested and option 2 worked. (around 1:22 and 3;45).

    All now appears to be good. Thanks again for the suggestions.

    Cheers

    Dave

    Thanks for your feedback. Please download this driver:

    https://catalog.s.download.windowsupdate.com/ms...

    This is a cab file. When you get the file, please open the file and extract the content, next right click on CIR.inf file and select install. Connect the keyboard and reboot the computer.

    Hi Dave, my name is Jose, a Windows user like you. I'll be happy to assist you with this issue. Sorry to hear you're experiencing this issue.

    Please verify if the manufacturer provides a driver for this keyboard. if not, please go to https://www.catalog.update.microsoft.com/ and verify if a driver for your hardware can be found here.

    Thanks for the reply Palcouk

    I bought the new machine without an OS and installed a licensed copy.

    I have a dvd disk from AMD, but haven't used it. Any driver updates were downloaded via microsoft.

    There are 13 updates shown from AMD in the update history.

    I've just checked in Device Manager and there are no warning anywhere.

    Regards

    Dave Johnson

    Was the pc supplied with 22H2 or did you update to that?

    You used that PC makers shortcut on your system to update both bios and all drivers from that makers update utility?

    In Device Manager there are no yellow warning marks?
