I just got everything in my NZXT Vulcan and for some reason both oh my USB thumb drives aren't recognized, Windows 7 Pro 64-bit says if it doesn't work after replugging then it has malfunctioned and to replace the drive. This is happening on two of my thumb drives that I've verified are fine on different machines. This problem is happening for both the case's front USB ports & the motherboard ports. I looked up this issue on the web & it says to uninstall all of your USB drivers and let Windows reinstall them, tried it and didn't work. Reset the CMOS, didn't work. Yanked the power supply cord out for about a minute, didn't work. Pretty stumped right now, anyone have any ideas?
