I am using the „bulkloopauto“ example. It is working fine on a Windows 7 64 bit machine. However, when connecting it to a Windows XP 32 bit computer, the FX3 is unable to enumerate. If I force the FX3 to enumerate in HS mode by calling “CyU3PConnectState(CyTrue, CyFalse)”, the FX3 enumeration succeeds and the application works at HS. The controller is a Renesas 720200 chip with firmware 22.214.171.124 and driver 126.96.36.199.
Apart from compiling the host aopplication in 32 bit mode and using the x86 driver from Cypress, is there something else that I need to do to get it working on Windows XP?
Did you get a chance to look at the USB trace when you connect in SS mode to findout the root cause.
