Why cant I access OTG and USB type C on my Samsung Galaxy Note 8?

I can't seem to find a solution on why I can't access files on OTG's and USB type C on my Galaxy Note 8. The device I'm connecting to my phone works with other devices including computers but when I connect it to my phone, there isnt even a notification that it was connected. I tried turning on the USB debugging in the developers option but still not working. My charging works well, so i guess its not the charging pin? PLEASE HELP!!!!
