Bummer.  It said on the kernel page that 2.2.20 has the driver (which
is obvious since it sees the device).

Any particular reason why?  I've got the sources, maybe I can hack
something and fix my problem?  When I do a write() to the /dev/ttyUSB0,
which routine in ftdi_sio.c actually gets it?

I've got a lot of stuff that will probably break if I go from 2.2.x to
2.4.x, and since usb is already broken it's easier to just fix that!

If it's hopeless, and I'm screwed, I won't have much choice.  But I'd like
to know why.  Thanks!!
