DM6446 USB PING control

Is there any way to disable PING's during CONTROL transfers on endpoint 0 when using the USB controller as the USB Host?
The other endpoints 1-4  have the DISNYET bits, but there is no similar bit in HOST_CSR0.

    Hi,

    Sorry, the disable support is not available for this device. The core version for this device is 1.3. The support was installed starting core version 1.4.

    I understand your problem. The earlier controllers did not anticipate for this issue and were not designed to be capable of controlling this feature directly. The USB 2.0 spec was not clear about the PING support for the Control transfer allowing user discretion to come on play. It was very clear about the PING support for Bulk transfer. So, not all developers had the support for the control PING transaction.

    Best regards, Zegeye
