Kévin Redon 5db9402a5f add serial and version info in USB description
as for the main application firmware, the DFU bootloader firmware
now also has the unique chip ID as iSerial in the USB description,
and an additional empty USB configuration indicates the firmware
version (e.g. DFU bootloader version).
these are only visible when the device is in DFU mode.
