why can't i use otg on my one plus three?

[AC Question]

i bought a type C OTG cable and a 64GB USB 3.0 pendrive. I've enabled the otg in usb&storage and storage settings but it still won't work.
I've asked around and they have hesrd that USB 3.0 pendrive is not compatible with one plus three.If this is true then which USB type is compatible - USB 2.0??

You will need the OnePlus USB C adaptor, or the Xiaomi USB C adaptor.
