We are trying to develop a USB hub that supports AOA (Android Open Accessory).
The approximate structure is shown below.
Android Tablet ---- STM32 MCU ---- USB HUB IC ---- USB Devices(4EA)
The reason for this development is to let USB communication and charge together.
Since there is no IC that supports AOA among existing USB hub ICs, I will play a middle role between USB hub IC and Android tablet through STM32 MCU.
Please help me.
