Is anyone else here having trouble with USB 3, and does anyone have any workarounds? I'm trying to use my WD drive with this laptop. I got it to detect it once in USB 3 mode (according to system profiler), but now it doesn't want to. I can get the system to see the drive if I push the USB cable in just enough that the USB 3 pins don't make contact but the standard pins do. But of course in that instance it runs as a USB 2 drive.
