Hi

This is Herrick Oh at Ezsys in Korea.

My customer found CRC error problem in web camera that we supplied to them.

We used CX3 with bulk data transfer firmware (using CyU3PDmaMultiChannelCommitBuffer).

They checked it with Beagle USB 480 ( https://www.totalphase.com/products/data-center/) to check CRC.as the picture below

My customer's host is

1)     Kernel : 3.4.39+

2)     Android System : 4.4 kitkat

Did you see similar cases?

I hope to be informed how I can start to solve the issue.

Regards

Herrick Oh
