APC UPS losing comm with 12.04

When I start up my recently updated ubuntu unix (now at 12.04) 
all works just fine and apcupsd and multimon.cgi and apcaccess 
report good data.  After about 30 min (rough guess) the system 
console reports:

Aug 28 14:33:13 ubuntu3 kernel: [98814.108038] hub 2-0:1.0: 
unable to enumerate USB device on port 3

and apaccess says status: COMMLOST

The usb plugs are tight.
I did have this problem before I updated from 10.04LTS

Anyone have any suggestions on how to debug/fix this ?
