I found this :
"Driver is enabled but has not been started on XP"
you need to reinstall the driver swenum.sys but first you must create a .inf file for it):
"copy machine.inf from %windir%\inf to a temp dir
remove line 20: ExcludeFromSelect=*
add new hardware have disk (select the temp dir with the modified machine.inf) and install the plug and play software enumerator"
