    I think your connection is having some problem. Try reconnecting the cable. If it is the same after multiple attempts go to settings search usb preferences and check whether you'll be able to choose any of them. If all of them are disabled try reinstalling Oneplus drivers on your pc.

    Clean the USB port of your phone. This happens because there is no good connection between the phone and the cable.

    Hi everyone,

    I have the same problem on my one plus 3. Seems like I am not the only one in this situation. Cable is clean (I red some suggestions about checking it but it is clean) and I have tried several ones, most of them are new so I don't think this is a cable issue. When I plug it to my computer it doesn't ask me to connect to the computer like it used to do before. Computer doesn't detect it either even when I am going to configuration. It charges but this is the only thing it does.

    Version is OxygenOS 9.0.5

    I really need to download files to my computer so I can free space without sending everything to Google drive and download again from the computer an so on, this is a big waste of time.

    Even in the settings I cannot change any USB preferences. Nothing works.

    I tried to reboot too, nothing is happening.

    Help please

    Thank you very much for your help

    Dude, you can clearly see that your phone does not charge on the screenshot so either you have not plugged it in to the cable or the connection between the cable and USB port is unstable due to the dirty/damaged port.

    My bad, it's just that I did the screenshot when it wasn't plugged. But it is exactly how the USB preference menu is when plugged to the computer, I just wanted to show how the USB preference appears. When plugged I can't change it and even when connected to the computer with many different cables. Tried different computers and cables

    It can still be dirty/damaged USB port.
    I had the same issue.

    Then it could from the USB port of the phone and not the cable as I tried several new cables, but it seems clean...
    Got a good technique to clean it?

    Take a toothpick, make it thinner and try to gently scrap the dirt inside the port. That's all I can tell you.
