minicom or openocd command won’t run without root permission on a Ubuntu 16.04 system.
In the past, I was able to open serial port without root permission.
I verified that the current user exist in dialout and plugdev groups. Also, I don’t know if it matters but since this looks like a USB issue, I have three USB dongles – Wi-Fi, Bluetooth, and Logitech Unifying receiver connected.
Any thoughts on what could be going on?
