CGMiner recognizes the sticks, but they don't mine.
./cgminer -o stratum+tcp://peercoin.ecoining.com:3336/#skipcbcheck -u blackbird.2 -p 12345 --compac-freq 150

what are you running the sticks in .
A powered hub?
that reading you have does happen.
run 1 stick for 10 minutes and see if you get some valid hash.
