I don't think USB precludes NKRO, see this: http://geekhack.org/index.php?topic=17458.0 http://geekhack.org/index.php?topic=17458.0

  It does. USB can't report enough keys being pressed at the same time. So keyboards that support n-key rollover internally can only support 6 key when using USB: http://www.daskeyboard.com/product/model-s-ultimate/ http://www.daskeyboard.com/product/model-s-ultimate/

    The standard keyboard HID descriptor has room for only 6 keys (plus the 8 modifiers). In principle the keyboard can just define a larger descriptor, but not all hosts allow this. Some 'NKRO' keyboards pretend to be a hub with multiple keyboards attached, but at least some of these don't handle modifiers properly for hosts that don't merge all keyboard input into one.
