PSoC4L support only Full Speed transfer a maximum of around 1 Mega Byte/Second.So, please ensure that the transfer rate is not above the limit.
Can you share the Protocol analyzer log and the Creator project.
Thank you for getting back to me so quickly.
When calculating the transfer rate, would you include the data in both directions? If yes, it looks like 8 Bytes are transferred over a period of around 5.4uS, which would give a transfer rate of 1.48Mbyte/S…unless I am missing something.
I attached a text file of the captured data around the time that it failed. The first IN transaction that gets no NAK is packet number 12833715.

Yes, when data is transferring in both directions , it will be included in calculation of transfer rate.
Full speed device can have Maximum Effective Data Rate as 1.2 MB/s only as told in this AN too (page#11):
Full speed can devices can't handle data transfer rate higher than that and can NACK.
