Adding a second USB port to a STM32L476 based product.

Question asked by Norman Davidson on Oct 3, 2017

We need to add a second USB port to a STM32L476 based product so that the produce looks like a USB device to two seperate USB Hosts.

As the STM32L476 has an integrate USB2.0 port, is there a method that add a seperate second USB2.0 port. The product is a audio device and we need to accept audio over USB from two seperate USB hosts.
