Presumably you refer to a USB-C hub. Perhaps your hub is not fully compatible with your iPad.
You may need to seek assistance from the manufacturer of your USB-C hub. Check the specifications and stated compatibility. USB-C hubs that are not explicitly stated by the manufacturer as being compatible with iPad may be unreliable.
