This is wrong. There is no usbhid-ups-PingvinUPS.pid file, although  
the UNIX domain socket is there. The only way how I can explain this  
is happening, if that you've started the usbhid-ups driver in a shell  
and somehow lost control over that shell while it kept running. Only  
when running in debug mode, no PID file is created since the process  
is running in the foreground so you can easily stop it (Ctrl-C).
