HI, the  two USB2 ports on lattepanda v1 no longer work. the usb3 is working. In the windows control panel about peripherals I can see two roots USB concentrators the first one has a problem and the second one is ok. I've tried to uninstall and reinstall the one which has a problem : at first, it seems to be ok but after a while, the screen refreshes (in the control panel) and again a exclamation mark appears. could you help ? thanks
