If possible, run it in debug mode

     /path/to/usbhid-ups -DD -a upsserv7

and watch the output when it (re)connects. Chances are that the device  
is reporting different serial numbers (or none at all) depending  
whether this is the first connection made or a later one. We've seen  
such erratic behavior before on other devices. This will make it  
impossible for the driver to reconnect. You'll be specifically  
interested in lines with "Serial Number" in them (and a few lines of  
context before and after it).

Best regards, Arjen
