pi@luxonis:~/depthai $ ) the only advancment is that the depthai GUI does not crash and disapear ( formerly it was crashing and disapearing ) so i have tried to change some settings in menu like lowering the resolution and decresing frame rates from 30 to 10 with no success , the same dialog box with the same error !

Hi , currently i use HDMI cable to connect to screen display and the USB's are occupied by WIFI internet and the other by wiereless keyboard , how can i connect by means of USB .
