A USB adapter to RS232 connects serial devices with 9 pins (DB9) or 25 pins (DB25) to a PC with a USB port.
The cable connects directly to the computer's serial device.

If a Bootloader or D~USBLOGG is connected to the PC via a USB cable, the PC automatically recognizes a new hardware component and automatically starts the hardware assistant in case no driver has yet been installed for that device.
If the assistant is not automatically loaded, the installation can also be started manually. as long as the device is connected to the PC and the drivers are not fully installed,
The converter then appears in the Windows Device Manager in the form of \XXX USB UART\ with an exclamation mark in one of the lists \Other Devices,\ \Ports\ (COM and LPT) or \USB Controller.\
The installation can be started manually.
