USB Storage: data transfer failing with Status code -71

Hello Guys,

I am trying to create a duplicate copy of a file onto a USB 2.0 device (memory stick) connected to my SOC (system on chip) board. Basic idea is to test data transfer across USB host controller and USB Device. It is failing randomly after copying different size if file. I am attaching the log I got on the console (with some of my extra messages). In the log attached the failure happened during data being received by the controller.

After seeing the transactions by  hooking analyzer in between I am seeing the failure happening due to ACK not being sent by the controller in response to data (512 bytes) being sent by the device. And hence reset command is being issue.

Any kind of help is appreciated. 

Linux OS version used: 2.6.11
Device connected: USB 2.0 memory stick (similar behavior is observed with Hard disk too) -- in Hi speed mode

Here is the console log:
