Combatabilty Test Failed at DMA check

I just bought a brand new HP Pavillion A1473W, running XPMC and put an
ATI X600 AIW PCIE. I installed the Catalyst drivers and software, the
TV fails to initialize, and the Combatability test fails at the DMA
check. The diagnostic tells me that four USB HDS in my system are not
DMA enabled. They must be the four card readers in my sytem, all of
which must be connected to the MB by USB interfaces. I get the same
message whether or not there is a card in there or not. My Sytem
Manager/Hardware profile does not recognize these as HDs and does not
let me enable DMA for them.

Any thoughts?

Even though the diagnostic states that everything else passed and the
only things that failed are these "USB HDs"?
