Hi all. I did some projects around the STM32F103 managed by a GUI on PC, via USB. Now I would like to address more than one devices (STM32F103) by the same PC and the same USB cable. So the problem is how to give an address on the FW and how to identify any USB slave by the PC. Maybe is there anyone that can help me me? thanks a lot !!!

Make sure you report a unique serial number for each, and Windows with enumerate them uniquely based on that.

''address more than one devices (STM32F103) by the same PC and the same (sic?) USB cable''

I trust you don't actually mean that literally?

You do realise that you cannot connect multiple Devices to the same USB cable, don't you?

Each Device would need its own, separate, cable connecting to a hub - with a further cable connecting the hub to the PC...
