[ECOS] Re: USB Device support

[Nick - eCos Developer]

So far we have no experience with the chip. We are just getting started. I
was hoping that the sample WDM bulk mode USB driver in the Microsoft DDK
would provide most of the host side code. Am I wrong?
  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 ?
