U-Boot 2015.01 Pendrive [sama5d3_xplained]

Hi All!
I am using linux4sam-poky-sama5d3_xplained-4.7 and I want using a pen drive in u-boot.
The problem is that when I insert a flash drive is not detected (See Log).
This problem seems to have been fixed in later versions. I would like to know what the bug to fix in version U-Boot 2015.01-linux4sam_4.7 but I don't find that may be the problem.

If you don't know how to search the U-Boot mailing list, or retrieve module patches from the github, or generate a patch by diff'ing two versions of source code, then the simplest alternative is to use a later version that has the fix.
There are no dependencies in this case, so changing the U-Boot version to build is the prudent choice.
