LR1110 Host Aplication USB trouble

I´m installing the host app with the Geolocation Demo User Guide in a pair of LR1110 modules, i have installed python, pip and the lr1110evk-3.2.0.tar but when i´m checking the USB with the UsbConnectionCheck coomand appears a trouble that is not included in the manual issues (Error on USB line. Communication KO!) as seen in the left side of the screen shot, how can i correct it?
Thanks to all
