Yes, had swapped the powered hub and had the same problem.
Theoretically beefier wall wart: this one has a brick as opposed to a 
wart.  (Didn't check ratings.)

While the DVD does require more power and the front panel ports probbaly
don't have as much amperage available it seems the thumbdrives are the 
ones usually creating the problem; usually no problem when plugged in to
the front panel or the powered hub, just occasionally.
