If more than one device is listed, boot to Safe Mode > Device Manager and
"Uninstall" all devices listed in "Keyboards", otherwise continue in your normal
desktop.
In "Device Manager" expand "Keyboards".
Right click on the listed device and click "Uninstall" in the popup menu.
Close out of Device Manager back to your desktop.

Open either Explorer or MyComputer.
Expand to and delete the contents of:

C:\Documents and Settings\Your Username Folder\Local Settings\Temp
Click once in the right pane.
Press ctrl+a.
Press the Delete key.

C:\Windows\Temp
Click once in the right pane.
Press ctrl+a.
Press the Delete key.

C:\Windows\Prefetch
Click once in the right pane.
Press ctrl+a.
Press the Delete key.

Close out of Explorer/MyComputer back to your desktop and reboot.
Windows should redetect the USB Keyboard and reinstall drivers for it.

This solution worked for the guy who suggested it and it worked for me
Having the exact same problem described here with error code 41 an
working keyboard (usb and ps2) up until windows loads drivers. I didn'
even delete the Upper Filters entry, just the mention of lxsassc.exe.

Very last posting listed as solved.

(Quoted Text)
"I solved my problem by removing an item from the UpperFilters for th
keyboard in the registry. It's under:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Class\4D36E96B-E325-11CE-BFC1-08002BE10318
There was an entry for keykey which was leftover from spyware remova
action.
