as the title suggests, I cannot select a port as it is simply greyed out. I looked for a solution but it either didn't work, talked about a different operating system, or was too confusing for a newbie like me to understand.
A quick rundown: I have an Arduino UNO, when I connect it to my PC through a physical USB port extender the port option is greyed out, straight into the same port without the extender it's greyed out, and if I plug it into the SS USB port the same thing happens. I have not installed anything apart from the Arduino coding software. In device manager I do not see any Arduino drivers installed which could be important. However, I know it's not the board as it connects to my laptop just fine and I am able to choose ports.
I am very grateful for any help as this is quite a confusing problem to face before I was even able to understand the basics of Arduino boards.
(I am brand new to Arduino so please explain everything to me as you would to a 5-year-old child.)
