USB superspeed peripherals Forum Discussions

I previously posted here about submitting our CyUSB3.inf file for driver resale and was told to private message SrinathS_16 with the file. I have now found it is not possible to attach the inf file to a private message (only image files are supported as attachments) and have private messaged Srinath re my problems but had no response. I also attempted to reply to the standard EMail notification I received when Srinath responded on the forum (as the Email itself suggested) but that bounced. How do I proceed getting our driver inf submitted?

Hi,

Our company develop one USB2.0/3.0 testing equipment base on FX3, it simulate as a USB disk, and base on "Cypress\EZ-USB FX3 SDK\1.3\firmware\msc_examples\cyfxmscdemo"  to develop, the testing step as following:

1. FX3 create one timer

2. FX3 boot at USB2.0 mode

3. FX3 switch to USB3.0 or 2.0  when received a specified message, and record the current time.

4.  FX3 do NOT execute "CY_U3P_USB_EVENT_SETCONF" with the timer expire(The timer expiration value is 10 second), FX3 execute "CyU3PDeviceReset(CyFalse);"

the application loop to switch FX3 to USB 3.0 and 2.0, about run several hours, some times happen the timer expire, FX3 cold reboot, but FX3 hang up soon from the COM port log analysis. and OS can not get the FX3's token's package(refer to following picture, “要求装置描述元失败” in device manager).

Following is the relevant code:

....................................

   /* Create the required DMA channels. */

    CyFxMscApplnDmaInit ();

    CyU3PDebugPrint (4, "Calling USB Connect\r\n");

    /* Enable USB connection to host. SuperSpeed is not supported. */

    apiRetStatus = CyU3PConnectState (CyTrue, CyFalse);

    if (apiRetStatus != CY_U3P_SUCCESS)

    {

        CyU3PDebugPrint (4, "USB Connect failed, Error Code = %d\n",apiRetStatus);

        CyFxAppErrorHandler(apiRetStatus);

    }

DEBUG((4,"USB SPEED1=%d,%x\r\n",CyU3PUsbGetSpeed (),systemtimer));

CyU3PBusyWait (1000);

DEBUG((4,"USB SPEED1=%d,%x\r\n",CyU3PUsbGetSpeed (),systemtimer));

FX3StartConnecttime=systemtimer;
