lost ps/2 keyboard and mouse

[jim]

Hi, I am running XP home version on a HP pavillion 750
machine. I lost the use of both my ps/2 mouse and
keyboard. I am not aware of any updates unless they were
done through automation. I was able to work around this
problem by installing an USB mouse and keyboard. Device
manager says both ps/2 devices are working properly. I
have tried to uninstall and reinstall both ps/2 devices.
This did not work. I also updated the registry to allow
ps/2 devices to be hot pluggable. This also did not work.
The event viewer says there is an i8042prt event id 27
error. This occurs at boot up time. Documentation on this
error says the this is a timeout error and that I need to
increase the timeout interval in the registry for these
devices. Checking the registry shows these devices are set
to the default...12000 trys. I do not see how increasing
the number would help. There must be another problem. I
have also did a system recovery back to earlier dates when
the devices were functioning. Does anyone have any idea
what the problem could be? Thanks ahead of time!

Jim,
Sounds stupid but by chance did you unhook you mouse and
keyboard? Could you have hooked them back up backwards?

Z, Thanks you for the reply. The answer would be no. This
event just happened. The cables had been connected for at
least one year before this event happened. Now after it
happened,that would be a different matter since I have
been messing with thing doing everything I can think of to
fix it. But I did check that. Thanks!
