    Thank you.

    I've tried many methods but could not manage. I'm about to go crazy:)

    my sample code

    void USB_EndPoint1 (DWORD event) {

    switch (event) { case USB_EVT_IN: GetInReport(); fg_endpoints &= ~(Bit(1)<<16); //USB_WriteEP(0x81, InReport, sizeof(InReport)); OutReportBufCnt = USB_WriteEP(0x81, InReport, sizeof(OutReport)); break; case USB_EVT_OUT:

    OutReportBufCnt = USB_WriteEP(0x81, InReport, sizeof(OutReport)); // fg_endpoints &= ~(Bit(1)<<16); break; }
    }
