This allows certain mini-PCIe cards to expose parts of their functionality as a USB peripheral. This commit enables this third USB interface in the OpenBlocks AX3 Device Tree, and also adds comments on top of the two other USB interfaces so that the Device Tree makes it clear which USB interface at the SoC level matches which USB interface visible on the board.
