Not found modem connection to computer through USB

[jqhu27]

I followed the instruction to install the dashboard on Ubuntu 18.04 and clicked the dashboard_x86 icon to open the dashboard. However I kept getting 'Not found modem connection to computer through USB'. From the manual, I got the information that I need to install STM32. However, I just found the packet is used for Windows system. Is there anyone can help with this? Thanks in advance.

Hello,
You don't need to install any driver in Linux.
But you need to have rights for access serial ports.
Have you tried adding user to dialout group as shown in attachment?

Hi, I did do that before. But I still failed to find the device until I restarted my computer. Thanks for your help.
