There may be a possibility calling CyU3PDmaChannelGetStatus() and then comparing prodXferCount vs consXferCount.
However, I am wondering if there is a better solution, like some flag that is set once a DMA buffer overun occurs.

Hi,
You can use "CY_U3P_DMA_TYPE_AUTO_SIGNAL" to get the notification of the events.
For more details, please refer to "USBBulkLoopAutoSignal" example project.
Thanks,
sai krishna.

It looks like we don't have that option for AUTO MANY to ONE channel.
We may need to use MANUAL MANY to ONE to get notifications.
Thanks,
