Vantec is not a small company but that doesn't mean everything they 
sell is something they themself produced but might instead have 
slapped their label on it (http://www.vantecusa.com/).
 The current 
USB hub selections are shown at 
http://www.vantecusa.com/product-peripheral.html.
 They do seem 
confused between what is self-powered and bus-powered hubs (what they 
say for self-powered is actually for bus-powered).

Have you tried swapping to which USB ****ts these hubs are connected 
(i.e., swap them between themselves) to see if the problem stays with 
whatever hub in on a USB ****t or if the problem migrates with to 
whichever ****t the hub gets moved?  That is, does the problem move 
with the hub or remain with the USB ****t?
