Have you also tried setting

     pollinterval = 10

in ups.conf, to increase the polling interval for this UPS?

If this doesn't work either, I fear there is little else we can do for  
you. Occasionally, the connection may be lost (due to EMI, plugging  
other devices on the same USB bus, etc), but if this happens almost  
every minute, there must be something wrong.

The connection to the UPS should be fairly reliable, if not this is  
either kernel or hardware related. It doesn't seem to be the first, so  
your only other option would be to try this on different hardware  
(which would be a nice test, to see if you don't just happen to have a  
broken USB controller on your mainboard).
