I am designing a pad with imx6 solox which only has two USB interface and one PCIE interface.Now I want to implement a USB host interface and USB DEVICE interface, a msa interface SSD, and connected to Intel® Dual Band Wireless-AC 7260a wifi and bluetooth card with PCIE interface and USB 2.0 interface at the same time。I know the USB host interface and USB DEVICE interface can realize by Each via a USB OTG . and SSD can be implemented by converting PCIE to MSATA interface. so the question is coming ，How do I connect with ntel® Dual Band Wireless-AC 7260a?Should I expand the PCIE interface one? How to achieve it? Can I recommend chips and reference designs?Should I expand the PCIE interface one? How to achieve it? Can you recommend chips and reference designs?
