Using kernel 4.14.65, I get a usb-driver crash when accessing the top left port (topmost, nearest the ethernet port) of the Le potato.  Plugging any device into this port results in the following kernel message and prevents the use of usb until reboot.   There is no kernel stacktrace.  As long as I don't plug anything into that port,  the other 3 ports on the board work fine.  [  292.242434] usb 1-2: new full-speed USB device number 7 using xhci-hcd [  302.562341] xhci-hcd xhci-hcd.0.auto: x
