    CY7C67300 problem with SET_CONFIGURATION on windows XP

    johannes.walter
              Hello!   
         
      I just want to develop a small bulk transfer application on windows xp. I am using libusb.   
      The firmware on the CY7C67300 works and enumerates on the host. But when when i want to set a configuration the host hangs.   
      The output on USBTrace shows that a SET_CONFIGURATION command is sent to the usb controller. But it seems as the host waits for an response but there is none.   
         
      Do you know any ways to send an valid response to the pc? And how that response has to look like?   
         
      Thanks   
      Joe
