Hi Maulik, Thanks a lot. Here is more information: 1. Kernel is 2.6.29 2. It occurs on every copy files from other place to the USB memory flash. 3. It happens on every USB memory stick I have ever tried. 4. The issue is still there if I enable the "USB Mass Storage verbose debug" option in kernel. 5. It is fine to Copy files from memory stick to other places. I do not know which module cause the problem. There are SCSI,usb-storage and USB host controller driver involved in.
