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 ?
