Excuse me

I am a funs about u-boot. Something wrong about usb driver in u-boot. Some files(such as uImage about 7MB) in usb memory can't be readed during u-boot, while the other files(less than 1MB) in this usb memory can be readed successfully. Many usb memory also have the question.I have try the latest u-boot(2014.7).The problem still appears. The usb memory is DataTraveler 100 G3 16GB 3.0. The CPU board is koelsch. I hope you can get me some help if you have sometime free. Thank you very much. The debug Log is follow:
