    CRC error in USB packet in CX3 application



      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.
