In my case, I have to address a serial over USB adapter.

So, I would have to implement an OS-dependent method looping over all serial devices found (/dev/tty* or COM*), query them, wait for reply, then return a list of objects.

RS-232 serial ports provide no such functionality; it's merely a pair of serial lines allowing for asynchronous data transfer in any direction. You could attempt to probe for specific devices, but you would need what amounts to a device driver for each type of device that you would want to support, instead of the standard, generic HID interfaces provided on USB/Bluetooth.
