You're completely misssing the point. USB 3.0 is the new standard, it is backward compatible with USB 2.0 and 1.1, therefore the DWA-160 should have no problem working properly in a USB 3.0 port if the driver wasn't a POS!
My Linksys WUSB600N adapter has no issues operating properly in a USB 3.0 port, which is futher proof that D-Link needs to update their driver for the A2 adapters! In the near future manufactures are going to stop putting USB 2.0 ports on computers, so then what? Customers who own the A1 or A2 versions of the DWA-160 are support to buy a rev B? Not frigging likely when the B adaptors have the Ralink chipset and the Atheros chipset is superior!
