Subject: [usb] USB 1.1 Function Core and Endpoints Query
Hi
Over the weekend I tried reading on USB Endpoints, but couldn't get any
help so I hope someone from here can help me out. While the USB
Complete book is good, I'm having problem understanding some points.
This is with regards to USB 1.1 function IP Core by Rudolf Usselmann. In
his IP core he has defined 6 endpoints (usb1_rom1.v), which are 1
control, 2 Isochronous, 2 Bulk and 1 Interrupt. I'm basically looking at
implementing a bulk device so what I'm getting confused is:
1. Do the endpoints in usb1_rom1.v file and usb1_core.v file have to be
the same? What if I define all 7 endpoints as bulk in usb1_core.v file?
2. Do the endpoints in usb1_rom1.v file have to be defined as bulk
(in/out)?
I have tried both options and windows doesn't seem to like either?
Any advice please
Regards
Ash
