Scenario:
From Add/Remove Programs, IBM Director is uninstalled. Computer
reboots and *KABOOM* no local mouse or keyboard. If you remote into
the machine via RDP, keyboard mouse work fine. (I would also test the
hardware by booting a CD OS and testing there. I personally use
BartPE..)
Problem:
The issue, seems to be the UpperFilters registry entry for the
keyboard and mouse.
Solution:
For keyboard, fire up RegEdit and navigate to the following reg key:
[HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Enum\Headless\HeadlessKey
\1&1a590e2c&0&01]
In the right pane, double-click the UpperFilters entry and make sure
the ONLY thing listed in the box in "kbdclass" (mine also had usbkbex5
listed before it - i got rid of it)
The same technique for the Mouse: fire up RegEdit and navigate to the
following reg key:
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\{4D36E96F-
E325-11CE-BFC1-08002BE10318}]
In the right pane, double-click the UpperFilters entry and make sure
the ONLY thing listed in the box in "mouclass"
If you have no luck, try following these instruction that let me to my
solution: The test below is for kbdclass, but you can can use
mouclass just the same. Please POST YOUR FIX if it is different...
