I could not find any Qemu examples in FreeRTOS demos that would work with usb. There is a Qemu feature that is called USB passthrough which basically means, that you could make usb port on your host machine visible to Qemu. I have an idea of what arguments to pass to Qemu command for the purpose of usb passthrough, but I could not find any usb driver for FreeRTOS for Qemu, is there one? If not, would it be possible to write it for this purpose?
Not that I am aware of.
Feel free to share if you decide to write one
