USB C doesn't work with USB devices

The Hipad is unable to read an USB stick by USB C installed. I tried with many OTG drivers, but it is unable to see what is inside. It works just with keyboard detached and when you set one more time the keyboard the USB stick is not recognized anymore. The question is the following: the USB C installed on tablet works just as charger or is able to read also USB devices?

Hello, please contact the official email, thank you
