usb erupters always have hw errors normaly 1-10% of total shares

this is what it should look like



from the looks of yours only 1 erupter is getting any work and the rest are just sending out hw errors which means there not getting enough power to mine

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
