Cypress EZ-USB USB Console fails bulk file send to EP1OUT!

I'm trying to transfer a file to my Fx2 firmware using the Cypress USB Console application. I'm seeing that the USB Console application stops transferring after 64 successful 64-bit transfers have been made. My USB analyzer shows that the host simply stops sending. The USB Console shows "... failed" in its output window.

Can anyone confirm that this is a bug in the application? The application appears to have a bug that limits the number of 64-bit transfers to 64...

    64 bytes transactions?

    Don't confuse basic terminology.
    bit - byte
    transfer - transaction

    Do you mean
    "when you send more than 4 KBytes (= 64 x 64) file over EP1OUT endpoint, the EZ-USB USB Console (CyConsole) stops after 64th transaction of 64 bytes. No OUT-DATA-NAK is observed on the USB bus."

    What is the version of CyConsole ?
    I think the latest one is v1.5.1.1
