I tracked this behaviour down > to the CONFIG_USB_XHCI_PLATFORM kernel configuration. I have the same problem with the ODROID XU4, which also includes a dwc3 and an 8152 (it's probably dwc3-specific; the driver has been problematic before). I haven't checked whether CONFIG_USB_XHCI_PLATFORM=y helps, though.
