Thanks for the info! Just to clarify, we do not wish to create a driver visible by the entire system. What we are trying to achieve is a singular app that is allowed to control of the AX88772C and send USB packets to it. Are there any APIs that give an application access to a raw USB interface (Control and Bulk) in userspace? As a reference, within Android there is the 'USBHost API' which we have used to achieve this within that environment. Is there anything similar in the iOS ecosystem?
