Don't use that, it's not as current as what's in the 2.5.latest kernel.

If you only got 16 MB/sec from an FX2, your firmware might be improved.
I've seen 22 MB/sec from one.  The NEC controller can max out that
particular device.  Or maybe it's that you're going through "libusb".

Those NEC hardware limitations are fairly widely confirmed.  I'm told that
several of the other implementations (Intel, Philips, and VIA are now
available to various degrees; ALI, ATI, and SiS seem to be coming along)
are not taking those same implementation shortcuts.  But then, they're also
coming to market 18+ months later ... :)
