usb erupters always have hw errors normaly 1-10% of total shares
this is what it should look like

the best way to check would be take all but 1 erupter out of the hub and restart cgminer if it gets shares then you know it can use 1 miner then try adding a 2nd erupter to see if that gets shares if it does move onto the 3rd erupter again wait to see if it gets shares and finally the 4th
I did what you said and this was the result:
Usb 1:

How can 3 USB eruptors kill the power of a 3,5A USB HUB?
When every USB max needs 560 milliampere.
