The compac, or 1pac stick that I won arrived today.
Adding it to the usb hub didn't seem to work and gave errors like "chip not found (0)".
After restarting cgminer the others didn't work either.
After removing all sticks and adding them again the stick(s) worked fine after restarting the miner a last time.
Anther 11GH/s added... you never know where it is good for

Thanks again, Phil!
