Mainline kernel 3.8.3 for Mirabox

[ventura]

I am installing the Kernel 3.8.3 to the new GlobalScale Mirabox appliance. At this time I am using NFS root file system. The ethernet cards are fine but it seems that there are no support for the micro SD port neither for USB 3.0. The original kernel that come in the flash is 2.6 and everything works. I have some questions:

1. Where I can find the source code of firmware??? Until now I found only binary.
2. Should I be doing something wrong or the mainline kernel really doesn't have support for those peripherals???
