Keyboard port does not work unless connected intially.

We have several systems with Windows 200 installed and
touchscreen terminals attached. With touchscreen
terminals we do not need or have keyboards attached to
these PCs. Occasionally we have to reboot and without a
keyboard attached the keyboard port does not function. We
have keyboard wedges connected to these ports and thus
they do not function either and therefore are useless.

What can I do to allow the keyboard port to be functional
after reboot without a keyboard attached?

Are you asking whether it's OK to plug a keyboard in after the machine boots,
and expect the KB to work? Don't think so. Presence of KB is detected during
boot. Plugging in the KB after boot might even cause damage by conveying
static discharge into the machine.

You SHOULD NOT be plugging or unplugging hardware from the keyboard
port while the PC is powered up! PS/2 ports are not "hot" pluggable
or plug and play. It is possible to physically damage the controller
on the board by doing so.

If you really need to do this you could fit a KVM which will be
detected as a mouse and keyboard when the PC boots, and remain plugged
in to the PC even when you detach the keyboard. Alternatively you
could fit PS/2->USB convertors to your keyboards which will enable you
to plug them into the USB port, which is plug and play.

Hi Roger,

You really don't have many options. Your wedge should be able to
electrically emulate a PS/2 keyboard otherwise it isn't going to work. Can
you switch to a USB wedge?

I'm not quite sure I understand your problem.

Do you mean to say that when you first cold-boot the computer the
touchscreen and wedge operate just as you intend, but when you restart (warm
boot) the wedge is no longer functional?

I get that at some point both touchscreen and wedge work just fine and that
at some other point, the wedge stops working or is not recognized by the
computer.

What's the scenario where everything works as intended?
 
Even funnier that other folks have absolutely no comprehension of what they
read. You're way off base, Bubba. Before you come in here casting aspersions
on these good folks, make damn sure you know what you're talking about.
You're link to the Microsoft article ain't gonna help the OP one whit.
