Do any of the publically available recipes for the TWR LS1021a board support USB devices?

I have a TWR-LS1021a board that I have tried to boot an updated Kernel and filesystem image on.  It does not seem to have a functional set of USB 3 device ports though.  When I plug in a USB storage device or serial adapter neither seems to be recognised at all.  

 

When I started looking at the kernel setup few USB modules were included as part of the usual kernel or core-image-full-cmdline recipes.  So I started trying to build some in but do not seem to be having a lot of success.  

 

Do any of the standard recipes for the LS1021atwr board include support for the USB ports on the board and perhaps a handful of basic devices?  I was hoping to use them as a comparison for my efforts to see if I could spot where I was going wrong.  

 

My first guess would be that i need a better set of kernel modules to support USB.  I will keep working on that for now.  

 

My other guess is that I am still using an old version of u-boot with a new version of linux kernel and that is causing further issues.  It was already explained to me in another thread (eth0 (eTSEC1) On A LS1021a-TWR Board) that my ethernet interface problems were probably related to this.  If my kernel module twiddling does not work, I will bite the bullet and try to get either; a full boot from an SD-Card including loading an updated u-boot from there or update the U-Boot image in one of the device flash banks.  I have been putting off altering the flash images as it is nice to have them to fall back on but it has to happen some time.
