Missing keyboard folder in Device Manager

[Guest]

Archived from groups: microsoft.public.windowsxp.general (More info?)

I'm sure this problem is my fault.

The computer came with a basic Compaq keyboard and scroll mouse. I swapped
the keyboard for a Microsoft Natural Multimedia keyboard and the mouse for a
Logitech optical mouse (both of which we already had). Initially the keyboard
and mouse worked fine, but next day on rebooting the mouse was fine, but when
I used the keyboard both it and the mouse froze. In troubleshooting the
problem, I intended to remove the keyboard driver [which is currently
Microsoft PS/2 keyboard (Intellitype Pro)], but instead of doing it _right_,
highlighted the keyboarrd driver and hit "delete," rather than using the
correct uninstall procedure.

As it stands now, if I boot with the original OEM keyboard and Logitech
mouse, the device manager shows the folder for "keyboard," and the keyboard
driver is listed. If I boot with the Microsoft keyboard, the device manager
has no folder for keyboard drivers.

I've also tried removing (correctly) and reinstalling the mouse driver and,
per a suggestion from Compaq Presario support, downloaded and installed an
update for Terminal Services, and made sure that it was set to load
automatically. Their current advice is to go back to a restore point where
the Microsoft keyboard worked -- but, of course, it apparently never seemed
to work properly.

I haven't found any other reference to my problem in searching the Web.
Obviously somewhere XP has stored an identification for the Microsoft
keyboard, but I haven't found any information on modifying/deleting that file.

Any ideas or pointers to information?

Compaq Presario SR1020T, Pentium 4 3.06 GHz, 512 Mb RAM, XP Home w/SP2 and
updates.

Thanks,
Northe

Hi Northe

It's not the drivers but the "devices" in Device Manager I was
recommending you have a look at -- for instance, under Keyboards, at the
moment my Device Manager says: "Standard 101/102 key or Microsoft
Natural Ps/2 keyboard".

I was wondering if you might see a ghost of the Microsoft keyboard
there, as well as the one you have currently working. Remember you have
to check Show Hidden Devices in the View menu after setting the option
in the Command window.

Just out of interest, I checked my drivers, and I have the first 2 you
mentioned.

Is the problem keyboard a USB? If so, have you tried hot-plugging it in,
with the system running?

I did follow your steps, activated the devmgr_show_nonpresent_devices=1
function and the _Show Hidden Devices_ in the device manager for both user
accounts (both accounts have administrator privileges). Both accounts listed
only one keyboard device. In my case it says : PS/2 Keyboard (Intellitype
Pro) -- even though I don't have Intellitype Pro currently installed (removed
via the add/remove software function).

After that I opened up the device listing and that's where I found the
files I mentioned.

No, both keyboard and mouse are PS/2

Good luck -- let us know what happens.

We've got two of the same Natural Multimedia keyboards, and I've tried them
both with the same results.

I sure haven't seen this problem discussed anywhere else, either.

I _do_ appreciate your help, though!

Hey, you're welcome, Northe -- just wish I could come up with an answer.

Just as a very long shot, could you try booting up with the problem
keyboard and *without* your mouse? I vaguely remember reading something
about someone's keyboard not being detected when the mouse was plugged
in.

Other than that I wonder if if could be an IRQ problem causing the
keyboard not to be detected?
