Multiple USB instances on MCU with multiple USB ports about cherryusb_wch HOT 6 CLOSED

compiling one port c source means using this port , no need to select

from cherryusb_wch.

@sakumisu, thank you for your response. I understand that compiling one port's C source means using that port. However, I'm interested in running multiple USB ports simultaneously. Is there a way to modify or configure the code so that both USB instances on the CH32V307 microcontroller can be used at the same time? Any guidance or suggestions would be greatly appreciated.

You can use two USB peripherals, but you cannot use these two USB peripherals as both hosts or devices. You can use one USB as the host and the other USB as the device.

Is that limitation of library or MCU?
