Hi Rudi, I am writing a test-bench for USB2.0-function controller. I have mainly been modifying your USB1.0 testbench given at opencores for it. The function controller is accepting packets, giving ACKs correctly. But there seems to be a problem. Each time I send it a request, say SET_ADRESS it doesnt change the function address. More over when I looked into the code there was no module which was processing requests such as bRequest, wValue, wIndex etc. The usb1.1 code that you have given, all this functionality is present in the usb1_ctrl.v file. But in the USB2.0 there is no ctrl file which I could find. Hope someone can clear my doubts. Any help will be sincerely appreciated. best regards Anindita __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

Not available!
All processing of the USB data must be performed in software (by your driver). For the SET_ADDRESS function, software must receive and handle the command and set the register provided for the function address. On 9/27/05, anindita mukherjee m_anindita at yahoo.com> wrote:
