On the Cubieboard4 HCI0 is directly connected to a USB connector, and HCI2 is connected to a USB hub on the board. HCI1 is available with HSIC throug 2 pins on the GPIO expansion header, but left disabled just like on the Optimus board. This patch also adds the VBUS regulators.

Any thoughts on this patch?
It's similar to what I sent a few years back:
