    You might need a cable to connect to desktop, I purchase from Shopee or Lazada depending on the shopping app that sell the cable to you or even a Oneplus outlet.

    I also faced the same issue, try using type A to type c cable it is working fine now. only the stock type c to type c cable is not working with file transfer mode. not sure about other type c to type c cables.

    I used the type a to type c cable from oneplus 3t , now oneplus 9 pro is connecting on file transfer. it is definitely a bug.

    I have created a thread and also submitted a bug on the same. please submit a bug

    Yes Type A to Type C is working fine for me in my lenovo Legion laptop,

    Type C to Type C is working only on Desktop, not in my laptop,

    By the way, what you are using Mac laptop or a iMac or Windows 10 laptop? Tell me the brand.

    One more thing i noticed in the USB preferences page:

    While connecting through Type A to Type C , the USB preferences page have 5 options to select
    - File transfer
    - USB tethering
    - MIDI
    - PTP
    - No data transfer

    But with Type C to Type C, the USB preferences page have 6 options,
    - File transfer
    - USB tethering
    - MIDI
    - PTP
    - No data transfer
    - A button for charging the connected device(laptop in my case)

    I am not sure, if Oneplus 9 pro is considering my laptop as a portable power bank or a mobile device may be?

    Please check in your phone and update me.

    As you said in another thread, I think this issue is happening for Lenovo legion laptops?

    See one more person facing same issue with USB connectivity. But in this case both Type A and Type C is not working.

    Any comments?
