"The device sent an incorrect response(s) following a keyboard reset."
Just lately, the multimedia keys on my HP (Compaq) keyboard often do not
work correctly. Some keys (like volume up/down and mute) did still work,
but the on-screen displays are missing. The "internet" keys do not work
at all.
I noticed in the Event Viewer the error mentioned above occurs at a boot
up, source i8042prt, and this appears to stop the HP keyboard extension
driver KBD.exe from running correctly. All the normal standard keyboard
functions are ok.
On the odd occasion the i8042prt error does not occur at boot up, and
then ALL the multimedia keys work correctly.
As per suggestions on the Web, I have tried un-installing all the HP KBD
stuff, but the i8042prt error still occurs. I have also un-installed the
Windows keyboard driver (so that Windows re-installed it on next boot)
but the problem remains. I have also tried another keyboard. No
different.
I have even tried some suggested registry mods to increase the timeouts
in the kbdclass section, but to no avail.
Anyone any idea of where else I might look for the source of this
annoying problem?
Chris.
