Hi Bill,

I have written some general points below to be taken care of. If you have any specific issues/problems, mail me and I will be very happy to help you. For EZ-USB product we used the Anchor driver file. WE jsut created the inf file with our device information. I will have some windows driver queries soon.
We are designing another product with SH1 processor which uses PHILIPS USB device.
Thanks ,

1. When you try to send the descriptor information during enumeration, make sure that the descriptor tables are placed in internal memory. The SUDPTR registers do not operate with external memory. If you must place the descriptor tables in external memory, you may load the contents into unused endpoint RAM and then load the SUDPTR with the table contents like this:
ptr= &DeviceDscr; for (i=0; i< *ptr; i++)
{
*(IN1BUF +i) = *(ptr+i);
}
SUDPTRH = MSB(IN1BUF);
SUDPTRL = LSB(IN1BUF);
break;
2. Make sure to clear the EXIF register before clearing interrupt request, during OUT(IN for the device) transfers
3. Make renumeration Delay count 3 seconds. The Anchor example uses delay count of 1 second, and this has problem when the device is interfaced with the software in WINDOWS 2000.
