No.  Now I have and it does not seem to work,
but then I don't see the ttyUSB devices either.
I'm thinking that my kernel does not yet have
support and I need something newer.  (I know
I got ttyUSB devices created the last time
I tested the device....)

I'm sorry, I have to stop now.  I will try
to report back in a few days.  I hope I've
not distracted you too much.

I tried udevtest and didn't get any parse errors.
