I'm trying to develop an application for the STM32H750 using USBX to implement two classes on the same USB device: CDC ACM and MSC. I've managed to get each one working individually, but I'm having trouble combining them. When I connect it to a PC, n...

I'm using an STM32H750 MCU to run an application that communicates with a computer via USB in CDC ACM mode. The application uses USBX from Eclipse ThreadX and an external USB PHY (USB3300) to perform high-speed communication. My application works fin...
