It does help. At least we know it is not a permissions problem and  
that the driver is attempting to detect the UPS. Sadly, it failed. So  
most likely, your UPS is behaving differently from what we expect (any  
combination of baudrate, serial control lines and/or characters used  
for detection).

Well, what you could try to do is to capture the communication between  
the software provided by CyberPower and the UPS. On Windows, this can  
be done via PortMon

     http://technet.microsoft.com/en-us/sysinternals/bb896644.aspx

This can probably also be done under Linux, but I don't know how.  
Posting a 10 second log after startup is usually enough to get a rough  
idea if it is possible to support the device.

Note that CyberPower has been less than helpful in the past, so if NUT  
support is important to you, it is probably better to switch to a  
vendor with a better track record when it comes to supporting NUT.  
Without vendor support, I feel little urge to invest a lot of (unpaid)  
time to see what we should do to support them.
