Everything seems to be working fine. I've run 2 tests. For the Pogoplug V4, tested with a USB 3.0 thumb drive (PCIe is the host bus), For the Iomega iConnect, I don't have the Wifi Card or mSATA card (could not found one in my pile yet), so the test is just for MVEBU PCIe framework. 1st Test: Pogoplug V4 (Kirkwood 88F6192) <BEGIN log> U-Boot 2022.01-00458-ge120ef9f5f-dirty (Jan 14 2022 - 15:59:48 -0800) Pogoplug V4 <snip> pcie0.0: Link up Net: eth0: ethernet-controller@72000 Hit any key to stop autoboot: 0 Pogo_V4> usb start starting USB...
