Ensuring that there is an entry in the udev file is necessary, but not  
sufficient, to make this work. The udev file for NUT modifies  
permissions on the USB device, but the driver still needs to know that  
it can work with it.

The usbhid-ups driver in NUT 2.4.3 didn't have an explicit entry for  
09ae:2009, but along with the udev modification, you can add  
"productid=2009" to the ups.conf file. In the following thread, which  
you may have run across, Rory had added productid=2009 to the  
configuration file, but didn't have the udev entry:

One thing that we discovered is that the battery voltage reading is  
off by a factor of 10. There is no configuration override for this,  
but it is fixed in NUT version 2.6.0 and later.
