Either multiple instances of usbhid-ups running (are you attempting to  
monitor multiple UPS devices at the same time?) Usually the usbhid-ups  
driver will be started before upsmon and on most systems will have a  
lower PID (not a higher one). Could it be that you attempt to start  
the driver again without stopping the previous instance? Or the  
generic (non-NUT) hid-ups driver?
