Writing reports to a device from kernel? Why would that be needed? I even see no reason to do it at all. The virtual keyboard should live at the border to user mode or even fully in user mode. There should only two system devices (like in Windows) mouse and keyboard. Only keyboards are writable at all (mice may be writable, but not from the virtual mouse point of view). ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
