[ECOS] USB Device support

[Siegfried Schaefer]

Hello,
i do also confirm. I have to implement an USB driver with the PDBIUSBD12
coupling to a AT9140M400 for a customer of me and stacking most of the time
in problems of how to made the host (Win98) to speak with me . The interface
of the usbchip is very simple to program but we have had timing problems
with the parallel interface. It seems to us that the read/write signals from
the ARM are to constraint to the PDBI. We have now a solution working on 12
MHz :-(. I have posted a few months ago that i want to contribute this code
to ecos, but unfortunately i haven't got the time to do so. Now it seems to
me that ecos has done a great step forward since my last viewing of the
code, making it even harder for me to contribute :-(.What are your
experiences with ARM and this chip ?
