Following the example in STMCubeMx Azure USBx CDC ACM. it seems that I'm having trouble when the PC does not recognize the USB device slave giving me this error
the there is no error in the app_usbx_device.c initialization, in terms of memory allocation. during debug, checking the _ux_system_slave handle it seems that the slave descriptor is not set.
I don't think this normal not have the device descriptor populated. I don't think there is a problem with the hardware since I run tinyusb on this device no problem. since I'm migrating to azure RTOS its nice to use the USBX as well.
If anyone can shed me some light on this issue, I would really appreciate it.
