I need an electronic scheme or circuit schematics (I am not sure how to call it). I think it should be an easy project for a good engineer.
Basically, the final product is an 2 in 1 device involving an USB hub that connects that 2 devices. The smaller device is incorporated in the biggest one. The hub should be as well inside the biggest device.
I will give you details in private.
Thank you for your posts !
